I remember seeing a couple of posts about someone who had put thinner rims on the back wheel but can't seem to find it.

Can anyone point me towards it please.

Cant tell you the post or where it may be, but the thinner rime will be the 2.5". He got it from Talon - it was an old duffer - think his name might be Shep









:p

what about the front?

Does a narrower rim/tyre help off-road there also?

Hi - old duffer here

narrower front - no point.

You want a 2.5" rear which takes the 140 tyres nicely and makes tyre changes a lot easier. Improves grip off road as well.

There's a post on here somewhere all about mine and the problems I had (spacers!)

Yes I had a similar problem when I bought SM wheels for the ADV accept my problem was a lot more serious as i sheered of the rear caliper whilst riding............................

Not on here - on ADVrider

Oh, and the front is only pointless..............if you don't have one


:smokin:
ummm and what does that actually mean? lol that it is better or it isn't?

Is the narrower rim just stronger? or does it make a huge difference to off road traction?

Does it make the front more skittish on tarmac?

Im pulling Sheps leg!

I got the new front for a few reasons - my front rim was bashed to buggery and had a lot of dents. There was no way I was going to get it back into shape, and it seems that it is pretty soft. If you are hurtling along and then you hit a rock, chances are you will ding it quite badly. The new excel rim will be stronger for sure.

As for the narrower rim, yes I believe that it will help off road traction, and I am especially interested to see how it deals/alters the original spec when in sand or wet mud - will report back with that one.

As for the stainless spokes and the orange alloy hub........well theres nowt wrong with a bit of porn is what I say!

The oy reason I know of to change the front rim is becasue the standard KTM rims are soft and easily bent - although I haven't bent mine yet.

You would change it for the same size anyway - but a stronger excel rim and possibly a fancy orange bling hub :D I don't think the new rim would affect handling or grip at all.

The rear is changed for a narrower rim 2.5" to allow the more off road tyres to fit properly. if you look at a D908 type tyre on a standard rim it is very flat, the 2.5 rim allows it to be curved.

The traction with the 2.5 rear rim is a lot different. it seems to throw a lot of dirt up now and flings stones and rocks at anyone behind me ......... I think on a hard packed surface the wider standard rim and wide tyre offers more grip, the narrower rim can't dig in.

On a softer surface the narrow more rounded tyre digs in better.

I have found the rear much more controllable - the throttle control is better for finding the biting point on the edge of the traction .......... does that make sense?

Regarding the front, a narrower rim is stronger and less likely to get hit/bent. It presents less of a target to rocks, has a better cross section (more of a triangle) and is protected more by the tyre.

The same traction rationale for the rear (tyre shape) applies to the front. If I was getting dirt rims again, Id go for an A60 front... (bit of a faff lacing them up though)

I'm assuming you'd stick with a 21/19 setup? as I've seen a 21/18 setup or is that due to tyre sizes?
