Got a vespa px125 with a damaged cylinder so am looking for a suitable upgrade cylinder kit that can be bolted straight on without changing crank or anything else.
So what kit to go for and what to avoid?

Cheers

Was thinking Mallosi, bgm etc but apparently not easy bolt on and with the bgm you loose the electric start? Is that right ??

Keep the suggestions coming guys

Thanks Tony. Are these direct bolt on without any other mods needed?

Sell the engine and do a straight swap for the new Pinasco engine that would be my choice,
Other than that I agree with Tony

DR177 will bolt straight on to a standard 125 and doesnt really require the casing to be ported either, so if your crank and the rest of your engine is ok a DR is plug and play. You will need to upjet your carb, and a 22 tooth clutch sprocket will help you make the most of the extra "grunt"*
A standard PX150 cylinder and head will also do the same job, but to be honest i'd go for the DR.

Right unbeknown to me the chap went out and bought a kit, a Malossi 166 and brought it over with his engine, have to say it looks very well made hope it goes together ok.
