  • $599.00
    Unit price per 


Comes with High Performance Transmission for Better Power Transfer to the Wheels:

This is not a stock buggy engine.  It comes with the High Performance Transmission: 1500 PRM Spring and 10 gram rollers, performance variator and high stall clutch and thus more torque and more power due to more efficient power transfer.  You will not find this engine anywhere else.

Also standard:

  • Standoff for muffler.  No kick start to interfere with your exhaust!

  • Upgraded transmission!

  • We can upgrade to a 175cc or 184cc.  See options!

  • Longer drive shaft to accommodate a reverse gear box but will work without a gear box also.

  • Guaranteed Fit!






 


 

We can even convert your new 150cc engine into a 175 or 184cc racing engine:
