PJ, if you didn't get to ride one,...you didn't miss anything.

I raced my RD250 against the factory 600 proddy bike back in 74, the Silk never stood a chance.

Was Leslie Griffiths in Bridgend ?

Hi Sam, yep,
Ewenny Road Bridgend.
Honda, Yamaha,Triumph and MZ

Jubilee Bonneville was 'interesting'

Triumph went belly up and we got SILK, don't remember exact time frame, wasn't important at the time

I moved 'across the street' to Two Wheel Services, Suzuki, BMW, and, Vespa (and later 'new' Triumph, Suzuki, Yamaha, Ducati)
