Quick Overview

KX105 Stroker Specifications:
Fits 1998-Current KX85 and KX100

Product Description

Actual Displacement = 104.99cc

Engine Modifications Required:
Cylinder: Bore, Port and Replate with Apticote 2000 ceramic bore coating.
Power Valves: Modify for larger bore
Head: Rechamber to work with the stroker crank and big bore piston. 100 octane suggested for most conditions.
Crankshaft: Stroked and balanced.
Crankcase: Must be cleared for the stroker crank.
Blueprint: Calculate deck height, squish clearance, trapped volume, port timing and compression ratio and list on your perminant Spec-Sheet.

Notes: This kit requires you to send us your entire engine for modification, with kickstarter and shifter.

Notes: You must use a KX85 cylinder for this modification. We are able to get much more power out of the KX85 cylinder than the KX100 cylinder.

Notes: Prices listed are to install stroker kit parts in good condition engine. Should your engine need rebuild parts there will be additional charges. We will call for approval before we install any parts that will have additional charges. (example: mains, main seals, trans parts)

Notes: This package flat out hauls. Many people choose to go with the Hot Rods stroker crank and a KX100 cylinder to get 105cc because it is less expensive. That is a big mistake; you get what you pay for here. This is a full on race engine modification that is as durable as it is fast. It was developed by Rick Peterson and RPM's from 1998-2001. During that time it was used and tested by none other than James Stewart and the American Kawasaki armature program. It is faster and more durable than the KX112, KX119, and KX121 we also built for them. We can promise you, if you don't win with this kit it isn’t the bikes fault.
