BSA John McLaren TAG 350 ALL-ELECTRIC Off Road Competition Trials Bike

No petrol, no oil, no fluids, no noise, no heat, no smoke, no pollution, just simply no fuss riding with low maintenance and British engineering at its best!

John McLaren — BSA Company Ltd

Formerly with the John Player Norton Team, John joined the BSA-Regal Group in 1995. Since that time John has been the prime mover in creating several new motorcycles, both for BSARegal and non-European manufacturers. The BSA John McLaren carries his name as a fitting tribute to his services to the British Motorcycle Industry.

Seen here sitting astride the BSA Gold SR, another McLaren creation, John originally designed the frame and cycle gear for the BSA John McLaren as an off-road petrol driven moto-cross competition bike.

The TAG 350 continues to use much of John’s original design with some clever engineering by RIPE systems. The electrics have been developed by Weald-EVT (The UK speed record holders for electric motorcycles) The TAG 350’s quick-change battery cassette allows for hours of use and the five year no-quibble guarantee promises years of trouble free motorcycling.
