1966 - 350 cc RC173
The RC173 is a completely new motorcycle, developed concurrent with the 500 cc RC181. Both bikes are virtually identical. External difference : the RC173 has round camshaft covers, the RC181 rectangular ones. The engines have now wet sump lubrications, with external oil coolers like the RC149 and 166. The carburettors have cylindrical slides. However, bore and stroke are the trusted 50 x 44.5 mm of its predecessor, and the gearbox contains six speeds. The megaphones have very pronounced reverse cones. Power is 64 bhp at 13,000 rpm. The frames have now bolted-on, twin front down tubes.
