Royal Enfield's Turbo Twin used the Villiers 4T engine, which featured a more angular top end than the preceding 2T and incorporated cylinders with four transfer ports (the 2T had only two) and ported pistons. A Crusader frame was used while the cycle parts were those of the Clipper model. This Turbo Twin was restored in 2014 when works carried out included powder coating the frame, repainting the tank to a high standard and rebuilding the engine with a new crankshaft, cylinders and pistons/rings. Parts renewed include the electrics, wheel rims, tyres/tubes and seat. Last run in April 2015, the machine is offered with sundry restoration invoices, current MoT certificate and a V5C document. Handbooks and a box of spares are included in the sale, while the provision of flashing indictors is the only notified deviation from factory specification.
