Had a shot on this a couple of weeks back. Obviously not crazy power but was a nice wee thing and sounded great! Never seen one before. I’m guessing they never made the uk?
Japanese market only bikes but have been imported all over the place, I had many of the 400 versions. Very rare and collectible now the 250. Gear driven cams make them sound amazing.
My mate's Mrs in NZ had one, I didn't have a go on it, but it did buzz along nicely. I saw the FZR 250 version at one of the South Leverton bike nights last year.
Many years ago I had a 1988 Suzuki GSXR 250R, 4 cyl, 4 Stroke, 4 carb, 6 speed, 17500rpm Redline but would go to 19k rpm until drop off, was a fantastic little bike, if you redlined + every gear you could get 180kph out of it.
