My first year of racing was on a KR1.
I did reasonably well on it, for a novice.
I expected great things from my second year, especially getting the KR1S.
Unfortunately, it took a while to get it sorted.
I bought it with a full Harry Barlow tune, which was too peaky.
I eventually got it sorted by Stan 'the man' Stephens.
He transformed it to a flexible bike, with plenty of drive.
It used to spin the rear in second, out of slow corners.
Still needed copious amounts of Silkolene 'Pro-boost'.
Umpteen piston failures though.
The handling was difficult too, with the forks being particularly bad.
No feedback, so the odd crash and the dented confidence that ensues.
So results went down the pan, apart from one second place and fastest lap.
I switched to RGVs after that.
If I thought the KR1S was unreliable, the RGVs were a lot worse.
So much so I had to retire to due lack of funds and motivation.
I have seen this bike on the road, in my area.
Never found the owner though, unfortunately, or I'd buy it back.
