Lambretta Small Block RB20 200cc Racing Cylinder Kit Ø66mm - AF Rayspeed
The 'RB20' is compatible with the 125/150/175cc small-block Lambretta crankcases. 

  • aluminium
  • 7 ports
  • Ø 66mm
  • 2 piston ring(s)
  • w/o cylinder head
  • nikasil coated, with manifold and reed valve

One of the most advanced engine kits ever designed for the Lambretta.
The modern design of the 'RB' cylinders includes a number of updates for the Lambretta motor. The RB cylinder have a larger reed-valve assembly with the reed-petals arranged in two rows to provide an increased inlet cross-sectional area. To make effective use of the greater volume two 'Boysen-ports' are located between the reed-valve and the transfer ports. The overall port layout provides more volume than their predecessor, although there are slight differences between the cylinders in the range.

Kit consists of,
RB Cylinder,
Piston Complete,
Dual Reed Valve Assy,
Inlet Manifold,
Inlet,
Head And Exhaust Gaskets,
Six Inlet Manifold Bolts And Two Exhaust Studs.

"The RB20 Kit is made up of a 66mm cylinder, a two ring vertex piston kit, an inlet manifold, a dual reed block assembly, and a top end gasket set. This kit is intended to be fitted to the 125cc, 150cc, 175cc crankcase. Offering dramatically improved performance over the standard. This engine is very smooth and free reving making it easy to put the power down and exhilarating to ride. This is the highest level of performance we offer using the small crankcase. This kit will need a number of other main engine components changing in order to allow it to work and remain reliable."
