BIDALOT BID11000578 Thermal unit cylinder kit

We are always looking for more power, more performance and more speed, and tuning expert Bidalot from France is definitely one of our go-to manufacturers when it comes to high-quality, extremely powerful racing products. The Bidalot Racing Factory 50cc WR Derbi Euro2 cylinder kit is another milestone in the high-end 2-stroke tuning. The Bidalot RF50WR racing kit is a powerhouse inspired by and developed for racing, and has been successfully tested on international racetracks. The name RF-WR (WR = world record) refers to the 2018 world speed record on Lake Bonneville, USA. The Nikasil-coated aluminium cylinder has 5 transfer ports and an exhaust plus boost ports. Cylinder bore is 40mm. The cylinder head has a special coating and provides excellent cooling of the self-centering combustion chamber. The piston is made of a very heat-resistant aluminium-silicon alloy for extended service life. Attention : this high-end tuning cylinder has to be run with other appropriate high-end tuning components (internal rotor ignition, 28 or 30mm carburetor, V-Force reed valve, reinforced clutch)
you also need the matching Bidalot crankshaft with 39.7mm stroke and 85mm connecting rod. If you don't want to go all the way, we recommend to use the regular Bidalot RF50WR version (lower compression).
