Wharf Rat Posted March 22, 2021 Report Share Posted March 22, 2021 I remember towing a pal on a B40 in RAF livery after his zenor diode had cooked. He screamed for the full 25 miles home. The old XS650 pulled like a train. I took it steady, but he'd never been towed before. He was white as a sheet by the time we stopped. The 44 was the best Brit single ever made IMHO. Loads of torque and they rev like the bejesus if you have the guts to nail them. A real riders bike. Good luck with the sale. Link to comment Share on other sites More sharing options...
