SIP PERFORMANCE 60mm STROKE ROTARY VALVE CRANKSHAFT
£318.00 (including VAT)
VE10557 Sip Performance rotary valve crank - VESPA T5. Featuring an extended 60mm stroke, this crank optimizes capacity for any tuned motor. Specifications include a 60mm stroke, 115mm con rod, and inlet timing of 125°/-9° post TDC. Note: This crank is specifically designed for use with the SIP 199cc conversion cylinder VE10906. If paired with a cylinder that is not designed for this crank, the cylinder will need to be raised 14mm using a packer, as the con rod is 10mm longer than usual and the increased stroke adds 8mm to the piston travel, split evenly with 4mm up and 4mm down. Cross reference Sip 45106600.
