Variants & Setup

Jet size sets the stroke offset: a bigger jet number gives a longer stroke and more displacement, typically paired with a matching bore kit, head work and carb/throttle body tuning. Match jet size to your overall build rather than choosing the largest by default.

Installation & Package

Replaces the stock LC135 crankshaft; case, bearings and clearances should be checked/machined by an experienced mechanic. Jet 4mm+8mm set includes one standard gasket per seller; other sizes not fully itemized, confirm with seller.

Important Notes

This is a performance/racing modification part; verify road-legality before fitting to a registered bike. Fitting a stroker crank usually requires matching piston, cylinder and case work and is not a bolt-on to a fully standard engine.
