Kawasaki KX134 Big Bore Fits 1999-Current KX125

 

Product Description

Actual Displacement = 134.23cc

Engine Modifications Included:

Cylinder: Bore, Port and Plate.

Power Valves: Precision machined to clear piston.

Head: Re-chamber to work with the Big Bore piston. 100 octane suggested for most conditions.

Crankcase: No crankcase mods required.

Notes: This kit requires you to send us your cylinder, head, and power valves for modification.

The KX134 is an excellent kit that provides substantial power gains across the board.  These used to be legal in the AMA 125 classes so we have built a ton of them over the years.

The Kawasaki KX134 kit mimics the stock power band but with just more power.  If you are a “125 guy” but just need more to hang with 250F’s this would be the kit for you.
