125-200cc Looking at buying a WRE 125

Hi all, I've been after a Husqvarna 125 for a little while now (preferably SMS), I've spotted a WRE for sale and I'm thinking of converting it to supermoto trim. What would I need to do this? On my Gilera RCR (Derbi Senda) I just swapped the wheels over as the forks were already quite firm. Also what's required for derestriction? I've read that there's a washer inside the expansion chamber and a carb kit it required rather than just a larger jet, is this true?
Thanks, Ryan

I've owned mine for 5 years wth 20 thousand plus miles on it, brilliant bike, best I've ever owned. How much is the one you found? To change it to supermoto literally just buy supermoto tyres of 120 90 18 rear and 90 90 21 front, fit them on with inner tubes or get garage to do it, no other mods needed. The only restriction I think is the exhaust and the cylinder porting, it's got 12 mm ports whereas the wr and cr have 18mm. I put a full dep on mine and had the carb rejetted with the needle raised up, has a 130 main jet if that helps you. It's quick enough just like that, 70 ish top speed 0 to 60 7/8 seconds/ If you've keeping the standard pipe, the washer is probably down inside the expansion pipe, might even need cutting in half to get at it. I'm not sure about a carb kit as such as mine runs fine with bthe 28mm dellorto, you could even try putting a cr or wr carb on, 38mm tmx I think. You can also put on the wr cr hoses, and take off the thermostat wire, it's better to run without it as if the thermostat sticks you can cook the engine

Thanks, the one I have found it a 2011 model with only 2700 miles going for £2200. Where's the best place for spares such as pistons and are the panels interchangeable with WR/CR ones as I noticed they are a different shape. Also is your dep exhaust originally for a CR?

not sure about the panels, they changed the shape after 2007 from what I have, try searching on ebay for a place in yeovil area, mdracing products I think, they had new ones imported from ufo that fitted mine, I think I recall they had later ones from other huskys too. Ebay is the best place for pistons, gaskets etc, I've run mitaka piston and gasket set on mine with zero issues for a year, prox and vertex were fine too. No my dep guy said it was specifically for the wre/sms of 2005, but they do a lot of different pipes so probably make one for your bike. I've seen cr exhausts fitted on to a bike like mine though, if you can find one, try comparing the pictures, it might fit straight on, providing the joining section between the silencer and the expansion pipe is in the same route[ some after market pipes go a different route to the original hence problems in interchangeablility]

Thanks, I went ahead and bought it for £2000. Here it is!
