Thanks for that Maarten..
I have checked out their website and there is a UK dealer which is good

Hopefully the bike I see later will be ok. I have spoken to a Honda dealer here today and found out how much parts are anyway for this bike. Here are some basic figures they told me:
Engine/gearbox - only sold in parts and would cost many ££££'s
Clutch - £100
Wheel bearings - front £22 - back £40
Brake pads £25 each front and back
Piston ring set - £40
Big end bearings cannot be changed - whole crank has to be changed if they are bad - £641
The bike I am looking at is £995...
