There's a 325cc kit from Thumper Racing (see the threads in the modifications section). We're developing a proper 350cc kit at the moment which will hopefully be less troublesome.
Sumo thread here:

www.ttr250.activeboard.com/t62898704/more-pics-of-my-ttr-supermoto/

but it's not a straight wheel swap. Best way might be to get some spare ttr wheels and have them rebuilt with 17" rims?

Welcome to the forum!

 Not tried them. Where did you read it - was it a reliable source?

This thread might help http://ttr250.activeboard.com/t44801045/supermoto-conversion-very-easy-alternative-wheels/

Sumo thread here:

That would be awsome even a300 would be good , iv heard some truly terrifying thing about the diy conversation . what piston would it run? Will it be a full top end change ? Would the carbie need a lot changed ? Will the ttr drive gear Han na power bost ?

The largest overbore using the standard barrel gives you 263cc I believe. The 325 requires a new sleeve in the barrel, plus machining of the gearcase to accept it. Top end (head) is unchanged. Carb copes fine but we think it runs a bit rich so smaller jets required.
This from the faq page:

www.ttr250.com/

The 350 we are developing will have a completely new barrel to avoid the hairline crack issues associated with the 325. Awaiting first proof-casting from the foundry at the moment. Watch this space!

Ride safe,

Simon.
