Description

O.S. Speed R21GT Combo Set L-OS1CC01

The new O.S. Speed R21GT L-OS1CC00 engine has been introduced to compete in the 1/8th scale GT touring category – with O.S. clearly looking at the IFMAR World Championship.

Performance has been improved over the entire range compared to its predecessor, the 21XZ-GT. The crankcase is a refinement of the R2101, which has an excellent battle history in on-road racing. The cylinder/piston uses 5 scavenged ports plus 3 exhaust ports that have cleared IFMAR regulations. The new crankshaft design has an emphasis on pick-up by press-fitting the DLC coating and counterweight that inherits the OS Speed tradition. Considering the GT touring racing scene, O.S. have adopted a new outer head that improves cooling performance. The engine is fitted with a new design 22E (B) GT carburettor that is a double adjustment type that emphasises pickup performance that smoothly follows the rise from each corner, which is important in GT touring. The reducer meets IFMAR regulations.

This Combo Set also includes the T-2060SC + MB01-70 (M2003SC) tuned silencer set.
