BGM PRO MRB-Racetour 225cc cylinder for Lambretta 200cc
Mark Broadhurst has incorporated his experience from several decades of Lambretta tuning and over 1,700 tuned two-stroke cylinders into the development of the RaceTour cylinders. The cylinders are available with 195cc (65 mm bore) for the small 125-175 cc engine cases and with 225cc (70 mm bore) for the 200 cc engine cases.
The 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.
