I'll trade you my RM125 for it.

If not - I suggest you put knobby tyres on it. That should really help with the dirt and whatnot.

you're kinda stuck with the SM brake setup unless you can find someone that wants to trade their SX/EXC front end.

I figured as much. How much lower is the SMR suspension compared to the SX stuff?

oh that's less than I thought. Now the question is if I get dirt wheels for this thing. What do I do about brakes? Do I need to change the fork bottoms to standard mount?

Good question, I'm not sure. There might be a clearance issue with the spokes.

I would think there'd be more caliper/spoke clearance on a dirt wheel....?

IIRC it was more of an issue of smashing that big rotor or a rock or log, or constantly washing out the front cause you have too much braking power

they work fine ( not optimal, of course, but not washing out the front all time) in the dirt with a slick. Why wouldn't they with a knobbie?

Ofugit,
yeah it's got a radial mount fork bottom. Maybe I'll just buy a mx bike and keep this KTM too.

On the trails, for sure more likely. On a decently groomed MX track I can't think of too much that would do that.

and on the spoke clearance: My understanding is that the spokes are further out at the caliper because the steeper slope from the hub to the rim because of the extra spoke length.

There's a high school geometry problem in there somewhere.

Just ride it as it in the dirt. After trying it again this past weekend at RA, its alot of fun.

the 22nd? I might be stuck at work, Triumph Demo weekend.

Ottawa might be kinda hairy for an SM bike. I've been told Fox valley is better/more fun.

I'll see about the work schedule. I NEED to get dirt practice in. The dirt section is where I was getting killed at this past weekend.

Me and Tony are talking about going to Flyin Brian's (Near Woodstock) this Sunday. Its my anniversary so I gotta stay close to home but want to get some dirt riding practice as well. They have a TT and MX track so it will be good practice with the Sumo bikes.
