RT225 Cylinder with out Cylinder Head

BGM PRO MRB-Racetour 225cc 70mm cylinder (WITH OUT CYLINDER HEAD) for Lambretta 200cc engine cases.
Mark Broadhurst has incorporated his experience from several decades of Lambretta tuning and over 2000 tuned two-stroke cylinders into the development of the RaceTour cylinders.

These cylinders offer significantly increased performance and therefore more everyday usability and riding enjoyment. The power is available relatively early in the rev range and the kits have sufficient torque for longer gear ratios. The power delivery is very smooth, so that RaceTour engines feel like an original Innocenti 200cc engine, but with twice the power.

The carburettor is located on the left-hand side, as with the original cylinder. No changes need to be made to the frame or the add-on parts. This makes the RaceTour the ideal cylinder for anyone who doesn't want to change the look of their Lambretta but still doesn't want to sacrifice performance.
All necessary gaskets, stud bolts and small parts are included.
