This is one of the best bangs for the bucks for all of you TRX90 guys.
Once you install the 124cc bore kits, either Kitaco or Takegawa, this kits bolts on to the crankshaft and now allows you to run your stock TRX90 clutch basket.
No need to buy a $700.00 clutch kit to run with your new big bore motor, this eliminates that need.
The installation of this kit removes more than 3 pounds of spinning mass from your crankshaft
thus freeing up more HP that is issuable for your rear wheels.
This converts your motor to a semi-auto set up.

Holding down on your shift lever will be your clutch lever.

Kit includes the CHP drive gear, conical thrust washer, nut with oiling seal built in and locking washer to secure the entire kit.
An additional oiling tube will need to be fabricated, or you can purchase one from us, to insure you maintain your crankshaft lubrication.
