Description

Details

The cylinder that has been breaking records. It set new best times in the Italian Open Cup and also broke the 6-second barrier in scooter drag racing. Stage6 has maintained the GP transfer port layout standards, refraining from cross-section reducing 7 or 8-port designs. The 47.6mm bore conforms to the rules of most 70cc racing classes. The patented modular construction allows for very quick mounting of the cylinder to different engines via adaptors. Sealing between adaptor plate and cylinder is realized via a Viton o-ring, eliminating the tedious task of cleaning sealing surfaces and replacing gaskets. Once the adaptor plate has been mounted and adjusted via gaskets, it won't have to be readjusted. The CNC-milled adaptor plate bolts to the engine case and accepts the cylinder via the external studs. The construction of the R/T 70cc cylinder doesn't use any continuous studs, so the design of exhaust and transfer ports isn't subject to the restrictions of conventional racing cylinders and further tuning and porting reserves are available. Particular attention has been paid to the cylinder's thermal properties. The CNC-milled inner cylinder head is bolted at five points, each of them thermally stabilized by its own cooling pocket. Thus the critical areas at the studs that tend to lead to piston seizures have been eliminated. The flange firmly connects the cylinder to the exhaust via three bolts, minimizing the leakage of fuel residues. Fitting flanges are available for all common racing exhausts and do-it-yourself kits can also be supplied. The kit includes an exhaust flange that fits the Stage6 R/T exhaust.
