The purpose of this build was to create a long-term bulletproof Grom that would stand up to the abuse we put it through. From being a trainer bike idling for hours straight to 12 o'clock wheelies, we use it the way it was meant to be used. Here's the list of specs/modifications we highly recommend to keep your Grom running optimally. **No amount of modifications can replace proper maintenance**
Crash Protection: Subcage and 12bar: MKS Sub Cage + Peg Savers
Dirt bars of your choosing w/ appropriate risers: Pro Taper/ODI CR Highs, KLX110 Bars + Woodcraft Bar Ends + Solid Bar Bushing Replacements
Shorty Clutch Lever: RSC 1 or 2 Finger. The stock lever works fine as well if you can adjust/bend it to your liking with heat.
Tires: Anything other than the stock tires will be grippier. We love the Kenda Kozmiks for the price. The best performance street tire overall is the Dunlop TT93 GP.
Thrill Seekers Seat Cover: This is the biggest game changer for learning since it grabs you when you start to actually get to balance-point. The stock seat is sketchy/slippery if something goes wrong.
Chain Adjusters: NDC chain adjusters with spools + Low Profile Axle Sliders (Easier maintenance and swingarm protection)
Brake Lines: Stainless Front and Rear (Coremoto +1in Lines)
Front Brake: Brembo P34 + Chimera Adapter Bracket + EBC Vee-Rotor + Stainless Banjo
Oil Pump Mod: Grom Beardo High Flow Takegawa; Necessary when doing longer wheelies or rev-limiter coasters. (30-45sec+)
IMS Shifter: Easier to bend back after a fall. (Con: It can send an impact into the transmission in rare scenarios)
Suspension Front and Rear upgrade:
Rear: Avoid Ohlins across the board, Go with K-Tech, YSS, or Penske
Front: K-Tech or Racetech, For a budget option check our impulse movements option.
Handbrake Setup: Big Rotor Rear, P32 foot brake, and P34 Handbrake with an appropriate master cylinder RCS16 Clutch.
Throttle Tube: Modified R6 throttle tube or "Rev3 Throttle Kit"
Idle Adjuster: eBay adjuster modified or "Gopro screw"
ECU Flash: Regardless if you do any intake/exhaust mods you should get the ECU flashed to get that little bit extra power out. Even stock there's a noticeable difference and you retain your "sneak mode" with the OEM Muffler.
