Information and Details about the Two Brothers Racing - S1R Full System - Honda Grom
made by Two Brothers Racing
S1R Race Exhaust Systems
The all-new S1R exhaust is the latest state-of-the-art product from Two Brothers Racing. The new system features carbon fiber highlighted by a natural finished Aluminum outlet and stamped spring-mounted inlet for ultimate durability.

The S1R exhaust from Two Brothers Racing showcases a brand-new design while increasing all-around performance. The beautiful new look is courtesy of TBR's innovative high temperature carbon fiber weave, while the performance is supported by TBR's constantly improving technology.

S1R New Features:

  • Aerospace high-temp carbon fiber
  • Teflon coated magnesium end-cap
  • Stamped spring-fit inlet
  • Aluminum CNC Machined outlet
  • Rubber-lined styled mount
  • Spiral-wound perforated core
  • Accepts sound reduction tips

    S1R Carbon Fiber:
    All of our carbon parts are made with a high temp aerospace grade epoxy resin. The carbon fabric is made with a 33 million modulus carbon tow then impregnated with the high temperature resin under very tight tolerances. This allows us to make sure that the fabric is impregnated with the exact resin content every time. We then place all of our products in an autoclave to cure. We cure all of our products under full vacuum and apply over a 100 psi for the cure. Using an autoclave allows us to consolidate the material and it also allows us to remove any volatiles from the material. This also includes any air that is trapped in the laminate.

    Honda GROM Full Exhaust System:
    With a unique bike like the Honda Grom, Two Brothers Racing has designed something special in the S1R exhaust. The innovative carbon fiber S1R exhaust will turn heads with a new design that has been developed to increase the horsepower by 10 percent and reduce weight by 5.5 pounds over the stock exhaust. The S1R is also fitted with a lightweight spiral wound perforated core and high performance sound absorption packing material. With noticeable horsepower gains, a lighter overall weight and that striking TBR sound, your Honda Grom will get noticed at the next Honda Grom Prix. Works with stock fender and Two Brothers Racing - Fender Eliminator Kit - Honda-Grom.

    This review is for Two Brothers Racing Fender Eliminator Kits - Honda CBR600RR - 2007-14
    Looks so much better BUT - Bret   MA Recommended by Reviewer: Yes
    Pros: Easy to install and look great
    Cons: No need for extra blinkers and the plate lights are very fragile don't tighten hard

    Kit comes with a set of blinkers ,that r not needed because I just reused the original ones that keep the factory look .i also stripped the plate bulb screws ,very fragile .i also used all the original wiring because I disassembled the rear tail section that comes off and reused the plate light from it.LOOKS WAY BETTER than packaged stuff and no need to splice wires .the kit really only needs the plate holder section the rest is fluff,and that should only cost 25.other than that yes I would buy again and yes I would still toss out most of what I bought
