Howdy
Whats the pros and cons regarding converting enduro wheels to SM wheels ????
03/11/2003 at 15:04
the pro's.....
cheaper......
they deffo fit without probs as they are OE hubs.....

Cons.....not many, only poss ones are
NO enduro wheels now
Hubs not as pretty !

No cons then apart from not havin any crosser wheels !!!!!!

ALL tyres can go off road...............its just the level of grip that changes....

can i still fit a 310mm disc to my wheels to improve stoppers,obviously with bracket

310 is beringer stuff....S'pensive...most peeps go for a 320mm disc and either an adaptor bracket to retain the stock caliper or a new caliper full stop.

You can't anodise cast hubs.

Another Con is that the hubs can break when stressed supermoto stylee. XR hubs have been known to break and Mad Roy broke a KTM hub as well. They aren't made for SM.

Errmmmm but they are OK for MX ????
Biggest prob is that some people do NOT leave enought slack in the chain..stressing the hub and breaking it....
IMHO , if a Hub is good enough for enduro/mx, it's good enough for SM.....

Funners, the XR prob is down to the spoke thickness although I suspect wheels intended for MX use stress the hubs less because of the inherent flex designed into the wheel. Also, do MX wheels not have less spokes than road wheels? This used to be a problem with converting old CR's in that more spokes were needed to stop the wheel flexing too much.

Read that in a September 1876 copy of RiDE.

Or don't mebbe check that all the sprocket bolts are as tight as they can be before each track session



I wouldn't worry about the hub's suitability for SM either - like the man says, if it's good enough for enduro/MX........ ........I got a new Yammy hub laced onto the rim and it's been fine (so far)

I would venture that the real problem is that SM spokes are shorter, therefore stiffer than the longer MX spokes (I'm fairly sure that, on KTM's at least, the spokes are the same gauges on either), which transfers more of the torque to the hubs. Or I could be talking out of my ar$e.

I bought an xr 650 that had some excel rims 19"/18"and Avon street tires with it, mounted on the xr is a stock 21"/18" knobbies with the same ebc oversize disk as the excel 19". The the guy did tell me he had never put them on, so dang it when installing the front 19" the axle was way smaller than the bearing? I removed my xr front bearings thinking they were the same outside diameter, they are not. (XR is smaller just enough) The part number for the ebc disk i found indicates it is for a crf 450 R4/R5/R6/R7/ (04-07) could it be that the streetbikes use the same front hub/axle as crf 450s.
And, what the heck can i do? Im on a skinny budget so any ideas would be gladly muld over.....the rear wheel came with an xr axle and bolted right up.
Your say
