I have in my shed a frame, swingarm and tripple clamps for a Spondon RS250.

When I purchased the frame I emailed Spondon in the UK and they confirmed only that these were converted TZ frames and mine was for a 1997.

I could not get any more info out of them and I am keen to know more as there is nothing on the net.

I hope someone here can offer me information?

I am based in Australia so they (Spondons) were not raced here in any great capacity although the RS250 were raced.

I need to know if I must only use a 1997 engine or if they interchanged right through.

Cheers
