For what it's worth I ride a very noisy quick (relatively) Thruxton. The handling is quirky at best. But it's fun. But for shopping and everything else. I have just finished a custom K75..... with K1100 'box ,diff , s/arm and forks, cut down frame, GS1150 spoke wheels shod with radials. It's the best thing I have ever owned. Smooth as silk , comfortable, reasonably fast and I scrub the edges of the tyres with ease. Only trouble it's as noisy as a sewing machine! Oh well you can't have everything
