Lambretta bgm PRO MRB RaceTour diaphragm piston kit with 70 mm diameter.

Complete piston kit consisting of: Piston, two steel piston rings of 1mm thickness, piston pin and clips.

The piston is exclusively manufactured by Meteor.The piston is the perfect choice if you have converted your RT 225 cylinder to diaphragm and are looking for a durable and long-lasting piston with windows and cutout.
In addition, the piston is the perfect piston for the TS1 cylinders. When used in Monza cylinders, the flatter combustion chamber geometry of the Monza heads must be adapted to the contour of the bgm piston.

The piston is coated with MoS2. A coating that provides protection during the running-in phase and disintegrates during this phase.

The windows are reinforced on the inside.

The piston crown camber corresponds to the original camber of the Lambretta pistons.

The coated steel rings supplied are extremely shatterproof and torsion-resistant. They are therefore also suitable for very wide and high exhaust shapes.

The weight of the complete piston kit is 285 grams.
