[hillclimb]

Hello I'm new to the forum, My name is Paul Dahley and my 14 year old son and 16 year old daughter hill climb motorcycles. I pick up dirt bikes when I come across them, that interest me. I have a 1982 ktm wr250.I can't find out much about this bike. The frame number is 107 3029 and the engine number is 541.Questions that I have is this motor the same as the 542 in the mx. Does wr stand for wide ratio. Was the wr a desirable bike that people wanted. The bike has twin rear shocks and is in pretty good shape. I have pictures but don't know how to post them, could email them . I would like to know a little history about the wr's. This bike is to nice to hillclimb. The airbox boot to the carb is cracked up, I would imagine that is impossible to find.Thanks for looking or any information about the wr's.

Hi Paul,

The 80's KTM bikes were either GS (enduro) or MC (moto cross) models.
The frame number indicates that it is a 1981 built in July.
The engine type 541 indicates that it is a 250 GS with a piston port cylinder. If your cylinder has a reed valve, then it would be a type 542 - 250 MC. Both the 541 and 542 engines have the same bottom end. The only difference is the the top end.

The 1981 250 have an exhaust pipe that crosses over the top of the cylinder head and out along the right side of the bike. These have the twin shocks.
The 1982 250MC have an exhaust pipe that snakes down and around the front of the cylinder and then up and along the left side of the bike. These were the first KTMs to use a single shock.

What you have described indicates that your bike is a 1981. I carry replacement airbox boots for this. give me a call 216-651-6559.
