SCK Crankshaft Stroker Kit (+3mm) - Yamaha R15 V1/V2/V3 /T150/Fz150i

SCK Racing Long Stroke Crankshaft Kits are great solutions to increase the performance and torque your machines. These kits will increase your engine’s displacement (cc) for great performance gains. The crank webs are reshaped and optimised for the best engine balance and vibration reduction. These kits come assembled and balanced with enhanced and strengthened con-rod kits.

• Increases total stroke by 3mm (1.5mm up+down) 
• Connecting Rod length - 98.5mm 

Note: For R15v3/V4/MT and similar VVA models, you need to add a 1mm bottom spacer/increase spacer thickness +1mm as the standard rod is 1mm shorter(99vs100mm). You will also need to reuse the stock bottom crank timing gear.
