This kit works perfectly for a 2018 Vader/Boom/Boadiao 125CC. I paired this kit with the race cam for big valve heads and a Mikuni VM 26 carburetor. Prior to installation, I could barely reach 50mph. I have about 100 miles on break in so far and I was able to hit 60mph with ease. I can even accelorate speed uphill in 4th gear now. Power wheelies in 1st gear are rediculously easy now. I can’t wait to see what this thing can do after break in!

Next step for my grom clone is a performance CDI. (The rev limiter kills the top end now) and 18t front sprocket. I think I will be able to hit 70mph with ease and cruise at 55 without wrapping the bike out. Highly recommend for the price.
