BGM PRO RACING CRANKSHAFT 54mm STROKE – LARGE TAPER 24-25
£150.00 (including VAT)
VE10543 BGM Standard 51mm stroke crankshaft - V90-100-125. The 51 mm stroked version of the BGM crankshafts is the maximum and perfectly suited for racing or ambitioned road riding, the crank has full circle crank webs and is only for use with reed valve induction cylinder kits.. The larger diameter of the crank webs support a larger overlap for the big end bearings. This allows additional safety against the crank twisting. PLEASE NOTE In order to fit the larger diameter crank webs (87 mm on the flywheel side and 86 mm on the drive side) you have to machine the casings to 88 mm. The next innovative feature is the piston rod length which has been increased to 105 mm (8 mm longer than on standard 125 cc Smallframe cranks). The crank is a perfect fit to some of the latest Smallframe tuning kits that are designed to be run with this sort of piston rod. Delivery complete with 8mm spacer, to keep the transfer times of certain cylinders the same, and longer and well build cylinder stuts for a save fit. This results in better power and reduced primary compression, which works well with the modern day exhausts, as the port transfers at the casing can be improved and the flow optimized. -strong crank webs -less twisting danger -optimized flow -higher primary compression -less stress to piston and bearings This is a large taper crank, with a 12mm flywheel nut thread and uses a 24mm flywheel oil seal and a 25mm flywheel bearing.
