We stock over 2 SR 190
The SR190 is an excellent kit in terms of durability and speed but it is let down by it's cost. The original piston (not used) was designed to be able to fit straight on to a 107mm con rod but we are having to use the proven TS185 pistons. These pistons have a shorter crown height than a Lambretta so you either have to shorten the barrel or put a longer con-rod in the crank.Unfortunately, due the mild tune on the ports during manufacturing, we cannot offer the shortened version so you have to budget for a crank with a 115mm Yamaha con-rod OR to have a 115mm Yamaha con-rod in your crank. |
