Right this is my question .. my standard rims only reli allow shitty off road tyres that on a 40 mile round trip most days.. if and where possible i would like to put some nice road tyers on it..

Here is my point if i could was to get some 18" supermoto wheels and take the center hub out and changeing it with the mtx center hubs... if this is possible this is what i need to know

Thanks Brad

You can get good and very capable road tyres in trail sizes. Easily enough to get my knee down and more a dr600 (obviously need a reasonable bit of lean to get your knee down.)
I've done thousands of miles on trail rims with road tyres and plenty of people have gone around the world, spending many hours in the saddle every day.

There probably are some road rims that with different bearings and a caliper bracket could be made to fit.
This is presuming you're not planning to use it for 'real' supermoto - ie races which involve on and off road sections.

Also, supermoto wheels are pretty much always 17". You probably already have an 18" rear wheel as it is!

And yes, as per Mike, you can get rims laced to your wheels. Likely to be the most expensive solution.

Yeah definately look into some decent road tyres for the std 21"/ 18" rim sizes if it's just better roadholding and braking that you want. Then you can easily switch back to off road or trail tyres somewhere between the two if you want to use it off road.

The 17" supermoto rim idea is mainly just better for the style and ease of obtaining real proper sticky race or track day tyres. On a purpose built Motard then wide 17" rims are obviously the best way to ensure a decent tyre choice for track use etc.

On a cheap and old bike with std trailbike suspension and brakes, then 17" rims are not going to be much of a benefit, especially as the forks and swinging arm are probably going to limit tyre widths to sizes that are not available in the stickest sports bike compounds and designs.

Im sure that Pirelli did the MT65 tyre in 21" fitments for the front of trail bikes, and i found them to be a really good grippy tyre for my CG125, so if you can get a set of those or whatever the modern equivalent is (City sport demon?) then id definately give them a try, and i think you would be massively please with the improvement over trail or proper off road tyres for road only use. steering, wet grip, and acceleration and braking should all be a bit better TBH!
