My MC21 project is coming along nicely but I need a few answers to my wheel selection problems.

I have a '92 SE chassis with a 2002 RS250 complete front end just getting the stem work done now.

The rear wheel is a '92 standard. 6 spokes of 'U' section, slightly offset and facing left / right alternately.

The front Marchesini is so similar that you need close inspection to tell the difference. It just looks more modern and neater. It also runs a 120/70 instead of 110/70.

I will be running with the heavier rear and lighter front (and fatter) this summer and would like both to be a matched pair.

Are there any rear wheels to match my front out there?

I would also like to run a 160 instead of a 150 on the rear to wed better with the front. Will this cause any chain fouling problems?

If I cannot find a matching rear I am prepared to look at a pair of new matching lightweight wheels.
I like the look of some Dymags I have seen. Will I encounter any fitment problems?

What other aftermarket wheels suit the bike?

Loads of questions. Any chance of loads of answers?
