Gran Turismo 250cc  Kit.

Run with our pre jetted  Dellorto

We road tested the GT250 kit for many thousands of miles before it was released  and still run a ported version on one lambretta.

We offer full build and tuning options on all of the GT kits, contact us for more info!

If fitted to a standard lambretta engine case, a small trench is required in the crankcase to give clearance for the throw of the 64mm stroke crank.

GT engine cases already have a sufficient trench as standard.
