Hi FazerSharp... Under the seat cowl the seat is cut away... bit like a Transit now..
LOL... It clips underneath across the brace at the rear and I've fitted a lock which connects to a brace I concocted at the front of the cowl.. a bit Heath Robinson.. but it's worked for years... Along with the high level can (originally a LeoVince.... I was wearing through the original on the front lip) the seat cowl was one of the first mods to be done.
Deefer did his all in one rear end and did the spraying... and I've mounted integrated indicators to the rear lights... standard rear mudguard, but cut away around the old indicator mounts.... that's it really for the rear end...
Nearly forgot... I fitted an old tank bag that zips on and off to the cowl like an enduro back pack... it was just to throw a few bits in whilst I commuted.... not a fan of wearing a rucksack.... The base is just bolted to the cowl...
