I just bought a nice rider/racer TM250 and need to get it from Liverpool, NY 13088 to College Park, MD 20740. Anybody on here planning on making that trip in the next 4-6 weeks or know of a good shipper?

The guy I'm buying from has an even nicer one signed by "The Man" himself.

Is that the same model that Roger Decoster raced?
Thought you might like this video...

Oh I doubt Roger ever rode a TM (except maybe for a promotional photo shoot, or testing). Also Mr. DeCoster mostly competed in the open class and on works bikes (In fact his Suzukis were responsible for the FIM adding minimum weights to the international rule book). He may have ridden 250 in the Florida Winter Series a few times... That's a great little video! :)

Roger did ride for a TM 400 magazine test in 74 or 75.

The TM400 was the stuff of legend....
Big motor, wimpy frame and no brakes......
Talk about a recipe for disaster!

Heh! The TM400 Cyclone, AKA "Widow Maker". Yep, it's not unusual (still) to find low hour '71-'75 TM400s, due to people buying them, scaring the C**P out of themselves (or getting hurt) and parking the beasties because they couldn't resell them. In reality the TM400 only had three issues (two of which were corrected for the 1974 model year):

- From '71 to '75 the TM400 had a light weight "pork chop"
crank and small ignition rotor, which mad it VERY quick revving,
rendering it difficult to ride in low traction conditions and making
the front end extremely light when it did hook up.

- For it's first three model years, it had a CDI ignition with a built-
in start retard timing feature that was somewhat random about
when it would switch to full power advance (there appears to have
been a temperature dependency) , but, whatever the cause, full
advance, and power, would arrive all at once somewhere over a
600 RPM range, which could make corner exits... Ummm... tricky,

- Also for '71-'73, the TM400 swingarm was WAY too flexible,
making the orientation to of the rear wheel a matter of much
conjecture, but little known fact for the rider's seat of the pants.

So we have a brutally fast, by the days standards, 396cc Two Stroke with very light flywheel, that had an unpredictable ignition advance & power curve, and a Flexible Flyer rear swingarm, with state of the, production, art frame, suspension, and tires; coupled with a low price and a large youth market as the later baby boomers hit their teen years... MAN! I REALLY wish Dad had invested in plaster and gauze in 1971! But this bike was easy to fix with common period upgrades. A flywheel weight, or TS400 ignition conversion (or TS400 crank), a TM250 ignition, and an aftermarket swing arm would render the '71-'73 TM400 no worse than the other open class offerings in most respects. For '74-'75 you just needed the flywheel weight or TS400 parts.

it is said the 1975 TM400 was no where as bad as it's predecessors from 1971 to 1974. the ignition system had a well known problem in suddenly going from near 0 degrees to 24 degrees in 1 fell swoop hence the violent burst in power. they did tame the 1974 model a bit but the 1975 model by then had a much better frame and a much better ignition system.

I got to ride a 1973 TM250 years ago that once belonged to a racer. it had been ported and when it came on the pipe it was very quick and fast. wish I had a 1973-74 CR250 at that time but I did have a very strong running 1970 DT1C that was stripped down into a dirt bike.

I could hang with everyone else we went on a rides with but it could not touch that TM250! by 3rd gear on the Suzuki he was gone!
