Hi everyone.

I've been searching for a decent MC21 recently, and after having seen a few rough examples, I've been offered an SP I like the look and sound of. I've seen a lot of photos and it does look very clean.

Its a late model MC21 on an L-registration, has a dated certificate for a 1994 and here is where I'm confused, the owner has given me the frame number and it begins with MC28!

Any idea why it would have an MC28 frame? It's got an MC21 swingarm, bodywork and all the trimmings etc.

The HPI check has come back clean, but it's not had an MOT or tax for almost three years. I'm trying not to be too paranoid about it, but I'm loathed to travel to the other side of the country for something that might not be what it's advertised as.

I appreciate that something that is 20-odd years old will have been modified or altered a little over the years, so I guess what I'm asking is, do you think I've got anything to worry about with this odd frame designation?
