Engine and transmission
The engine of the T10 was a development of the earlier Colleda TT, which had been introduced in 1956. The 180° piston ported two stroke twin was of unit construction and had cast iron barrels and an alloy head. Bore and stroke were  and the claimed power output was  @ 7,000 rpm. Ignition was by twin coils with points mounted on the end of the crankshaft. Power to the 12v battery was supplied by a flywheel generator and the machine was fitted with an electric start. Fuel was delivered by twin 20 mm Mikuni Carburettors. Primary drive was by helical gears to a multi-plate wet clutch. The four speed sequential gearbox used a 'rotating shift' mechanism; 'changing up' from top (4th) gear took the gearbox back to neutral. This was intended to reduce footwork when riding in traffic. Chain drive took power to the rear wheel and the chain was fully enclosed to protect it from road dirt. Cycle parts
A new frame was designed for the T10 which was of a pressed steel beam design. The engine hung from the beam with no frame parts coming down in front of the engine. Rear suspension was by swinging arm with twin shock absorbers. At the front telescopic forks were used. Brakes were drums front and rear, the front being operated by cable and the rear by hydraulics. The spoked wheels were both fitted with 300 x 17 tyres. A  petrol tank was fitted, which had a clear plastic pipe running up the front to show the fuel level, and a dual seat. References
