Here is a small 50cc kit from DOPPLER , this aluminum model named S1R will offer you many additional performances! DOPPLER has worked well on this product, fairly high diagrams, booster exhaust (3 ports), 5 transfers...
The exhaust outlet is unbridled and therefore round, the transfers are enlarged at the base, and the intake is much improved.
The supplied piston is a high-end two-ring model to maintain strength and torque. One of the best 50cc cast iron kits, to be accompanied by a high-compression DOPPLER cylinder head or a stock cylinder head.
The pack contains :
X2 piston clips
X1 segment
X1 piston Ø40mm bi-segment
X1 piston pin
X1 aluminum cylinder 5 transfers racing exhaust with boosters Ø40mm
X1 top engine gasket sets
As an option, we offer a stage 1 preparation. This preparation involves modifying the exhaust ports and ports by increasing the flow diagrams and improving the duct. This increases cylinder performance. This modification also includes an improvement to the piston and lower skirts. Please allow a little extra time for this preparation!
