Smooths the transition between the cylinders and the engine case. This form-fitting cover chromes the entire gap between the cylinder base and the inner primary. No more cast finish to discolor and get nasty looking. Clean-up on this area will be a snap compared to the stock roughcast aluminum, and you’ll add some major sparkle to the left side of your bike.

This review is for Kuryakyn Passenger Drink Holder - Harley Davidson Ultra Classic
Kuryakyn Passenger Drink Holder - RADAR322   Recommended by Reviewer: Yes
Pros: Good Quality, Easy to Install
Cons: none

Fitted to my new 2014 HD Ultra. Drink holder a surprise gift for the wife for those expected long rides. Nice chrome finish and sturdy holder. Instruction are well written, with clear type, colored pics, and very easy to follow even for a novice. Instructions suggest assistance from someone but with a little forethought and planning, its easy for one person. Read direction twice, and then follow each step. It all made sense in the end. Installation, while taking my time, was about 40-minutes. A much better value than some of the other option I shopped, and Competition Accessories promptly shipped within a few days.


This review is for Kuryakyn Crampbuster Cruise Assist
Crampbuster - VFR1200F   NM Recommended by Reviewer: Yes
Pros: Works perfectly as advertised
Cons: Hit gas tank when you turn all the way such as putting the bike in the garage

This worked well. It does exactly what it says, and you cannot beat the price


This review is for Kuryakyn Marlins Handlebar Mount - Universal
Great Clock - Frank   PA Recommended by Reviewer: Yes
Pros: Nice finish, easy installation
Cons: not a flush-mount

After a long search for a clock for our V-Star 250, we settled on this one. It was delivered very quickly with no problems. The installation was simple and took less than 5 minutes it is adjustable to about any position on the handle bar and the clock face can rotate within the case important as we decided to install it on a part of the handle bar that is not horizontal as the picture indicates is necessary. The clock is easy to read at a glance and nicely matches the speedo and tach same white-on-black. We did not opt for the style that can be read in the dark as this bike is not ridden during dark hours often.


This review is for Kuryakyn Premium ISO Grips with Throttle Boss - Harley Davidson - Cable Throttle
Great product - Dale S   ID Recommended by Reviewer: Yes
Pros: Easy to install and feels great on the road.
Cons: [None]

Although item was back ordered, when it arrived I was able to install within minutes. What a difference in the feel of the ride now. I used to have an old plastic paddle for my palm to rest on, but with the stock Throttle Boss, much more comfort and control.


This review is for Kuryakyn Passenger Drink Holder - Harley Davidson Ultra Classic
Perfecto - ChristoHD   IN Recommended by Reviewer: Yes
Pros: East Install, Looks Good, Holds almost any size, doesn't interfere with passenger getting onoff bike, has a good grip
Cons: Hope basket material holds up...

I installed this solo. Truly was an easy-install, toughest part is holding trunk open while removinginstalling trunk tether.Like the fact that there is a protective film for the paint on the bike where the unit could touch Looks good and best part is the Mrs. is happy to have access to a refreshment while ridingFit like a glove between the trunk and speaker pod. No slop. Nice design


This review is for Kuryakyn Mach 2 Air Cleaner Medallions
kurakyn medallion - pcap103   MA Recommended by Reviewer: Yes
Pros: looks great, easy to install, nice price
Cons: none

Bought the medallion to dress up a Cobra plain chrome air intake for my Honda Shadow RS. Fits perfect. Looks great.


This review is for Kuryakyn Longhorn Offset Dually Highway Pegs
Kuryakyn Longhorn Offset Dually Highway Pegs - SG Ray   NJ Recommended by Reviewer: Yes
Pros: Well made and easy to adjust to many positions
Cons: none so far

Installed recently then took a 1000 mile road trip was very happy to have them.


This review is for Kuryakyn Universal Electrical Power Point Accessory Plug
Great addition to my ride - Mike Arns   Recommended by Reviewer: Yes
Pros: easy to install, looks good, good price
Cons: [None]

installation was simple and it looks great. does everything as promised.


This review is for Kuryakyn Universal Drink Holder with Stainless Steel Mug
Nice addition to the bike - Thomas   Recommended by Reviewer: Yes
Pros: easy to install, holder is great
Cons: cup not the best. I use another one I bought from walmart

Overall I really like the mount and the system. The installation is very fast and VERY easy It might have taken me 5-10 minutes total. It comes with hardware for three different installs. So, it fits nearly any bike. It installs right on the mounting bracket for your clutch. However, the cup on the other hand is not great for riding a motorcycle.. The vent hole in the top allows coffee to escape on every bump i hit in the road had coffee coming up through that hole. Kuryakyn should have put a flip type lid like the starbucks or walmart coffee cups. Having said that, this holder holds a variety of cups, not just the one included with this bracket.


This review is for Kuryakyn Crampbuster Cruise Assist
Cramp Buster - chas   MN Recommended by Reviewer: Yes
Pros: Price, installation
Cons: None

This is a nice added feature, it let's you relax your grip and helps to reduce fatigue in your wrist and hand.


This review is for Kuryakyn Universal Kinetic Footpegs
PEGS - DON   CA Recommended by Reviewer: Yes
Pros: STADARD PEGS
Cons: THEY WORK.

GREAT


This review is for Kuryakyn Trailer Hitch - Harley Davidson Touring Models - 1980-2008
Excellent product - Acoustic   Recommended by Reviewer: Yes
Pros: Ease of installation
Cons: None

The product was excatly as stated in the ad. The product was easier to install than expected. I pull a small camper trailer with ease and I'm impressed with the quality of the product. I would definitely recommend this product.


This review is for Kuryakyn Harley Davidson Mud Flaps for Trikes
Bling - JasIndy   IN Recommended by Reviewer: Yes
Pros: Good looking
Cons: Installation

You want to take your time installing these as it requires drilling holes. This is not a complicated installation but does require careful measuring. These look GREAT. The flaps you get from HD are plain looking these give some snap to your rear end and protect. The fit and finish was perfect.


This review is for Kuryakyn Universal Kickstand Extension
Good produce - Curt   PA Recommended by Reviewer: Yes
Pros: Looks great when installed
Cons: None

Easy to install and solves the problem of putting the kickstand down when it's raining.


This review is for Kuryakyn Premium Ultra Tour Bag
large and compact - flyerdog   MA Recommended by Reviewer: Yes
Pros: size, shape, durability, rain cover
Cons: none so far

I've had this bag for a couple of years now and it has become my favorite piece of luggage. With careful and prudent packing, you can give yourself a weeks worth of suppliesclothes. The Kuryakyn roll bag fits perfectly on top and further increases your storage capacity if need be. The side pockets are HUGE and the amount of things you can store in them is impressive. I was able to fit an SLR digital camera in one of the side pockets. The Raincover is heavy duty and works in torrential downpours, it keeps the bag completely dry. As an added bonus, the bag is ergonomically designed so that it has a low profile and doesn't appear like a bloated sack on your passenger seatluggage rack. Mounting options are straight forward, with built in straps and additional ones included, so that secure fitment is not a problem...highly recommended


This review is for Kuryakyn Universal Skeleton Hand Mirrors
A Bone to Pick up - Stan from Belleville   MI Recommended by Reviewer: Yes
Pros: Unique looks, Standard Kuryakyn Excellent Quality
Cons: None

Excellent quality product, but I expect no less from Kuryakyn. Instructions are clear and concise. The only differences I noticed between these mirrors and the stock ones is that the arms are a bit longer and tend to induce a little vibration in the mirror head, not much, just a little. And, the mirror heads are a little smaller than stock. Both of these differences are quickly overlooked because you will spend more time admiring how cool they are rather than these small differences.


This review is for Kuryakyn Universal Throttle Boss
Excellent Product - JamesRussellPublishing.com   NV Recommended by Reviewer: Yes
Pros: Absolutely Functional
Cons: None

I have used this throttle boss on numerous cruiser motorcycles. It always fits due to the rubber stretch fitment and is so tight it will not migrate off the handlebar throttle grip, yet you can still adjust its angle anytime. The boss is not so large to catch on clothing which makes it safe to use. It is very comfortable. I even use one on my left grip as a palm swell grip. Once you try one of these you will love it. It really does take the stress off your hand muscles gripping the bars. I highly recommend them. Also, they last for years. The rubber does not fade or break down from ozone or UV light. And the price is right. Buy two


This review is for Kuryakyn Universal Arkon Motorcycle Gadget Holders
Phone stays dry - Tom   VA Recommended by Reviewer: Yes
Pros: Easy to operate an keeps phone dry
Cons: Mounting screw loosens quickly..

Nice product. Was used just so I can monitor any emergencies that come up. Brass screw that secures pouch to mounting bracket will come loose and dislodge itself so just tighten occasionally. Unfortunately I did not and I lost screw. I wish the manufacturer would have included replacement screws because without a replacement, it's worthless.


This review is for Kuryakyn Kewlock Grip End Helmet Locks
LockedLID  
the Kewlocks work great. My wife and I use them on our Arai Helmets. Much better than the cheap looking helmet locks you normally see. Plus you can not tell they are even on the bike when you are not using them.


This review is for Kuryakyn Crampbuster Cruise Assist
Cruse - Steve   NC Recommended by Reviewer: Yes
Pros: Easy to add on
Cons: Gits in way win you dont need it

Slip right on to grip and is easy to use


This review is for Kuryakyn Tri-Line Gauge Trim - Harley Davidson Touring - Trikes
Looks of the Kuryakn gauge cover for dresser - Chrome colored gauge cover for Harley   FL Recommended by Reviewer: Yes
Pros: Looks nice and dresses up the dash of the bike. Inexpensive and easy to install
Cons: Not certain how long the finish of this gauge cover will last

Just like the stereo cover I purchased, this gauge cover was easy to install and so far, looks great It was inexpensive and easy to install. I have ordered the matching control button cover as well, which goes under the stereo cover, but have yet to receive this. Hopefully Kuryakyn has made a product, that will withstand the elements of the sun, so in the future there will be no peeling issues to deal with.


This review is for Kuryakyn Tri-Line Stereo Trim - Harley Davidson Touring - Trikes
Fit & appearance of trim for dresser - Kuryakyn Stereo trim for Harley   FL Recommended by Reviewer: Yes
Pros: Not expensive and easy to install
Cons: Fit on the right side, where the door open on the dash for phone etc hook-up was a bit off

Kuryakyn's new part for the stereo is inexpensive and easy to install. I'm not certain as yet, about the wear abiltiy of this product since I've only had it installed for a couple weeks now. If the finish lasts and it does not peel off, it's a good alternative to the black dash color my bike came with.I also installed the gauge cover as well and it looks good so far.


This review is for Kuryakyn Mini-Grantour Bags
Good Product - S.S.   KY Recommended by Reviewer: Yes
Pros: Good storage in a small space. Looks good on my bike.
Cons: Straps didn't work for passenger seat application.

I looked at every bag available on line. Saw this one in person at HD dealer which helped because it gave me a better perspective of the size. Competition accessories had the best price of anybody I checked out. Plus fast free shipping. Very glad I got it. Mounted on passenger seatV-Star 650 Custom Looks good and not too big so as to overwhelm the looks of the bike. Don't care for saddlebags so needed something for lunch box for work and picking up things at store etc. Does the job. Only gave four stars because of mounting straps and hidden backpack straps. Back pack system is wasted space and makes bag taller. But I knew that was there when I bought it. Would be better if it was removable. I will never use it. Seems awkward shape for packing on back.


This review is for Kuryakyn Harley Davidson Chrome Driving Lights
Kuryakyn Driving lights - SG Ray   Recommended by Reviewer: Yes
Pros: Well made and easy to adjust to many positions Look great
Cons: Wiring is not a direct fit and the switch isnt either.

The lights work and look great. But the wiring is not a direct fit as they claim I own a 2014 Street Glide and had to splice in the wires and the switch does not fit the housing had to drill it out to fit the fat round toggle switch, the switch lights when turned on which is a nice feature. I am happy with the lights just know what your getting into.


This review is for Kuryakyn Premium Ultra Tour Bag
Perfect for a weekend 2up - Bird Dog   AL Recommended by Reviewer: Yes
Pros: Good size,rain cover,pockets
Cons: Weak fasteners, size of sissy bar strap

I bought this prior to a longer rider with my wife. The goal was to have plenty of storage on my Nomad for a long weekend. This bag did that perfectly. The side opening main compartment made loading easy and neat. The smaller side pockets are all the size of a toiletry bag when fully expanded, which is perfect. The rain cover did its job well, keeping our clothes dry despite a torrential downpour of more than an hour. The bag fastens securely, but the sissy bar velcro strap will just barely fasten on the nomads thick backrest pad. The other straps work well to make the bag stable. My only complaint is that the bag was delivered with a broken luggage rack plastic fastener. I deemed it not worth the money to send it back and will fix it with JB Weld or similar. Metal strap locks in that area would be great. This is right where they can be broken on some concrete or if the bag is dropped which I suspect happened in shipping.All in all I think buying this was an excellent choice. One person could travel for a week with it I suspect.


This review is for Kuryakyn Harley Davidson Traditional 3 Pouch Fairing Bag
Extra Pockets - JasIndy   IN Recommended by Reviewer: Yes
Pros: Provides the extra pockets.
Cons: Not water proof

Good instructions but not needed, very easy to install truely 15 minute job including a bathroom break. The magnetic snaps are great when you on the road and need to grab sunglasses etc. while your moving you can close the snaps without looking.


This review is for Kuryakyn Marlins Brake-Clutch Mount - Universal
Good Clock - Albertsdaddy   CA Recommended by Reviewer: Yes
Pros: Easy to see
Cons: Does not tilt up or down , only side to side

I use it every day to avoid speeding when I think I'm LATE I wish they made a head temp. gauge to mount on the other side,that would be perfect for my HD Sportster Custom .Only found Digital ones on Ebay ... I am a Analog guy I will try to make one because my bike is Air Oil cooled andthe engine temp. affects the performance quite alot Ride Hard or STAY home .... Jonathonsdaddy


This review is for Kuryakyn Trailer Hitch - Harley Davidson Touring Models - 1980-2008
HDBILL91 - Bill   FL Recommended by Reviewer: Yes
Pros: Great deal and construction
Cons: Directions a little confusing

Just wanted to thank my salesman for helping me and I will buy many more things from your company in the future


This review is for Kuryakyn GranTraveler Bags
nice but heavy - brent   Recommended by Reviewer: Yes
Pros: lots of pockets
Cons: heavy even when empty

easy to load and lots of pockets. plenty of strap on rings.may exceed your rack's weight limit


This review is for Kuryakyn Clix LED Pods
Rap-around Licence Plate Braket - Hammer#49   NY Recommended by Reviewer: Yes
Pros: Great change to the normal license holder.
Cons: [None]

This item is a sweet change from what the production bike has. My neighbor just bought a 2013 HD Street Gluide & promply replace his license plate bracket with the wray around vivid black style. Wow Now I will have the same.... 2005 HDDLI owner


This review is for Kuryakyn Universal Throttle Boss
throttle boss - jameskjr   AR Recommended by Reviewer: Yes
Pros: relieves wrist cramps when riding for longer trips
Cons: needs to be readjusted frequently

The throttle boss does help with riders cramps when riding on a longer trip. The only issue I have is that it has to be adjusted sometimes while on a trip cause it will slowly turn on you sometimes. When it does you have to let off throttle and simply turn it with your right hand. Just make sure theres no one on your tail when you do it. It is still not a bad investment for only 11 dollars.


This review is for Kuryakyn Trailer Hitch - Harley Davidson Touring Models - 1980-2008
Trailer hitch 1980-2008 - Floridabill   FL Recommended by Reviewer: No
Pros: none
Cons: Bad Insructions No hardware

The product looks good out of the box but doesn't fit on my 91 police bike. I was told it would doesn't come with any hardware for installing Terrible instructions Unit is too wide for fender no matter how I installed it would not align straight I am truly disappointed


This review is for Kuryakyn Kewlock Grip End Helmet Locks
Looks great but doesn't last - Vulcaneer   Recommended by Reviewer: No
Pros: Easy installation and looks good on the grips
Cons: Unreliable

After using the lock around a dozen times over the course of three months the unlocking mechanism sheered and the key would not release the lock bolt. This is of course very inconvenient when far from home. Have heard of this happening to many other people. The manufacturer will replace it, but it's not worth the risk of having a helmet protecting your handlebar rather than your head for the ride home.
