EXC Supermoto conversion questions

Hi, I have a 2011 (60 plate) 450 EXC Factory edition. I have been using it for Green lanes & some pay n play days. Now I want to SM it? The gearing is currently 13T on the front & 50T on the rear (what should this change too ?) I know the SM wheels will be 17" but what width would I need ? What tyre size ? Is there anything else that would need to change ? Would I need a new front calliper or just an adapter for the current calliper ?

All help & comments much appreciated, Thanks in advance,

Mark

obviously I’m putting tubes in them with the wheels being spokes so is this rim tape stuff I need special stuff ? Or is it just tape? Like duct tape or gorilla tape. Stupid question probably but not if you don’t know right 🤔

Demon Tweeks saves the day. Went over & got rim tape, inner tubes & a filter at the same time. They couldn’t fit me in to fit the tyres so I thought feck it I’ll do it my self. Can’t believe how easy it was.

Rim tape / tubeless. Lots of info out there about doing a tubeless conversion on spoked rims using 3M 4411 / 12N extreme sealing tape. I did it on some alpina wheels when they starting leaking at the spoke 0 rings. Many thousands of miles later, still good.
Oh right cool. Thanks for the info. I’m glad someone can actually say they have done it & how long it lasts as all the videos just say it’s done like this but then no time line info. Much appreciated

Great info pal thanks. My fork guards aren’t wrap arounds anyway & have a designed in type of cut out so I had no worries there. Got the sprockets & chain done & found the issue with brake disc bolt fouling on the caliper carrier, turns out the spacers are labelled wrong. Right is labelled left & left labelled right, swapped them round & all fits nice. I’m in work now in the process of fabricating a small part to reduce chain run on the tyre. If it works I will post pics & the CAD drawings I did for it so others can replicate. Can’t wait to ride it now. Again thanks for the info. If I get any punctures I will go down that route.

That’s all sorted now & in line perfectly. Can’t get this WS setting to work though now. Disconnected the 3 wire plug, get WS to flash but when I press + it does nothing. Then I got the Rb 2206 battery fault so I went & got a new battery thinking it was that, replaced it but guess what…..yeah still doesn’t work.

Haha guess what happened…………………was out riding yesterday, had done around 80 miles with regular smoke breaks. On the way home was sat at 50mph minding my own business when the engine suddenly without any warning what so ever made a loud crackling noise then a clunk & a pop & cut out. Got recovered home & left it overnight with out doing anything. Today I took the oil fill plug out & found bits everywhere inside. Looks & feels like metal particles. Now is it worth stripping & repairing or not. Do I try to find another motor. I’m presuming the repair bill will be over £1k.
