I've got to say that all the electrickery on new bikes really turned my stomach when I came back to biking. ABS, Rider Modes etc. and a host of non-user serviceable 'black boxes' ain't what I want in a bike. I want that fly by the seat of yer pants feel that bikes of my youf had. Back in the day I rode bikes that were absolute basket cases and never had a problem. One of my favourites has to be a really beaten up 1981 (or at least some of it's parts were) Kawasaki KL250 which I bought from a fella called Knoxy from Kilmarnock. He had put this bike together because he was on the verge of losing his licence on his GSthou and promptly got done for doing 40mph in a zone which had recently changed to a 30mph zone without his knowledge on her and decided to sell her on. The bike was started with an old car toggle switch that, for security was plugged into a pair of crimp terminals so that it could be removed to stop people stealing the bike

The forks were slightly twisted in one direction and the bars slightly twisted in the other, spokes were seriously rusted (I had two wheels collapse and I replaced them for ten quid a throw from the breakers in Ayr), the tyres were full off road knobblies, brake lever was snapped so was only about two inches long and the exhaust was a conical piece I cut from a silencer from a step-thru with a washer and a half inch of tubing welded on the end (no baffles) to make it look like a silencer (sounded like a Panzer on manoeuvres). The thing would do about 80mph and was incredibly docile. I frequently raced the wee dafties on their NSR125's etc. and left them in the dust and they often shit themselves when they saw me sticking a foot out in the bends to keep her upright when that big knobbly shod front wheel let go at speed. I swear that the few honoured people I allowed to have a shot on her (ZXR, GSXR, VFR pilots) suffered hair loss and hair whitening after just a short ride. How that bike got through an MOT I have no idea but I loved the thing.
I adore the fact that my 2001 Bonnie's are absolutely simple, apart from feckin bucket and shim valves and even my Sprint and Daytona are fairly simple apart from the Fuel injection system and basic on-board 'brain' and, once again, bucket and shim, pain in the ass, valve adjustment.
