It is definitely a 250cc bike but has a 4 speed gearbox, black USD forks with black 50mm tubes, no apparent lighting wiring, only a kill switch and 12/48 original sprockets.
I bought it from the 2nd owner who acquired it not long after it was first purchased and raced. He only ever used it as a trail bike and used it once or twice a year so it was as new when I got it just a bit knocked around. I can't see any evidence of it being modified from it's original purpose.
It has red plastics, GG on the top rear of the all black seat and no steering lock. 18" rear wheel Ohlins rear shock. The engine number starts with the EC prefix but I think all the EC and MC models were like this. Can anyone give me any further information about this model. All of the tech data I can find refer to the EC models, I'd like to find more about the MC if possible.
Cheers, Rob
The black 'Zoke 50mm forks were standard on the 2005 MC250. The VIN
number seems right. If it is indeed a 2005 engine, the cases and ignition cover will have a "flat" area above and behind the flywheel area, instead of the "rounded" area in that place as on the 2004 & earlier models.

The only real difference between the EC and MC (except for the MC having a shock with both high and low speed compression damping, the 50mm 'Zoke Shiver forks, heavier rate springs for the forks and shock, 4-speed transmission, and lack of a steering lock), was the crankshaft assembly's weight.
To explain: On the MC engines, the right side of the crankshaft came with a light weight aluminum spacer where the older ECs had the drive gear for the counterbalancer and the newer EC models have an 8oz balancing "cut" weight to offset the "throw" of the crank. (1999 & 2000 EC models had a fully round 10oz weight, that looked like the earlier counterbalancer drive gear with no teeth on it.)

The "early build" 2005 off-road bikes came with one CDI for the EC models and another CDI for the MC models. (My sometimes faulty memory tells me it was the more aggressive "black wire" CDI for the 200 that was used.)
The "later build" 2005 bikes, EC, DE, and MC, all came with the CDI compatible with the "rainy/sunny" (EC/MX) switch, but no switch came with the bikes until the 2006 models. If it has the switchable programming CDI, it will have two extra wires which will plug into each other (bullet plug ends on the wires) or go to the switch.

I didn't see any MC models imported with a 19" rear wheel after the 1999 year.
Also, you might like the 13/49 sprocket combination, or if you ride in the mountain single track, a 13/52. With the Messico pipe, the original '99 CDI, and 13/52 sprocket combination, my son Gabriel's 4-speed 1999 MC250 was measured by his enduro computer at '93 mph in the hay field section of the Red River Enduro in 2000. He was racing his brother Joshua, on his 1999 6-speed MC250, with the 13/49 sprocket set, across the hay field. Josh finished 1/2 bike length ahead of Gabe. We never got the bikes equipped with the FMF exhaust pipes and newer EC spec CDI to run that fast.

Anything I can help you with, just let me know.

Good Riding!
Jim
