This is our 2nd best choice for a performance CVT Transmission Kits for the GY6 125cc-232cc engines (in specific QMJ157, QMK161 & QML161 engines) . The only reason you should get this kit over our Ultimate CVT transmission kit is if you don’t like the chatter of the Reveno clutch or if you have a buggy / kart. The Reveno clutch isn’t preferred for buggy’s/karts because of the weight of the vehicle, so we 💯 recommend this kit. This kit comes with a forged TFC clutch and bell. It’s very strong annd won’t warp easily. We offer option for a pulley. You can use your old pulley, upgrade to our TFC steel pulley (much better quality and has adjustable slides), or go all out and get our light weight forged adjustable TFC Pulley. To top it off we include a performance Reveno contra spring, ProBld spring bearing, premium belt and ProBld performance variator. This is the complete CVT. The variator is our own ProBld variator. We did a ton of trial and error to design this variator. It has a light weight drive face with a fan (If you are running a CVT cover). We include 10, 11 and 12 gram rollers to dial in the CVT according to the weight. We even include a titanium nut and washers. The last step is to add the proper belt your kit. We include premium belt. They come in long case or short case:
LONG CASE BELT:
- Belt size will currently be 835-20-30 or 842-20-30
- if you have a scooter the wheels on your scooter will at leased 12 inches.
SHORT CASE BELT:
- If you have a GY6 with a shift lever you will have a short case.
- If you have a scooter your wheels will be 10 inches.
The goal of this CVT transmission kit is to install and go. All of the major tuning has already been figured out. Everything has been meticulously picked for this kit to be sure it’s great quality and performance is gained.
