    So after going to the Bash earlier in the year with my Grom Fatherz 210 build and drag racing it I decided I wanted to get a little more aggressive and set it up to go faster. I went a a [email protected] at the bash but knew with a few tweaks it could go much faster so the new build began.

    First I pulled the engine and sent it back to Grom Fatherz to do a once over as well as add a 5 speed trans, larger cam, and a even larger TB. White it was there I worked on the changes I wanted to make here. First I ditched the heavy stock swingarm with mojo stretch for a Gcraft plus 10cm arm. Switched out the brakes for Brembo P34s, Galfer wave rotors and, braided lines. Next I switched to lighter wheels and mitas MC35 tires. Swapped out huggers and multiple other parts with carbon replacements. Then I switch from Renthal Fat bars to a set of Drag Barz and added a 2” front fork drop kit.

    Finally we did a retune on the bike with MR12, and with the sticky tire likely soaking up a HP on the dyno made 34.6Hp.

    With all said and done first retest of the bike at the track netted a [email protected] After a few tweaks I improved that time testing on the dragy to a [email protected] and a [email protected] I will be headed back to the track tomorrow to back up the new time with another slip.

    Thanks a lot to Kenny at Grom Fatherz for all the support and one hell of a engine. The bike went a GPS confirmed 107 on the old setup. Will rest the new setup very soon for too speed.

    Amazing! I would love to see the reaction from people racing in cars, when you beat them down the 1/4 mile.
