hi, know jenny had a set of talon hubbed wheels, though her front was based on the ktm pattern on a single disc i do not recall them being available in twin disc. when i did mine i also grafted a ktm front end on and modded for a lc4 rear setuphttp://www.xt660.com/showthread.php?t=14756&highlight=paddy to do the rear correctly the rim centreline has to be moved away from the sprocket.

bar the weight and the flexi cush drive why not just put the stronger rims on? i returned mine to near standard as i like the better brakes, tho using the 18'' rear allows me to kill off all the enduro hoops lying around

and yep the holes are different for trail and mx enduro use, i have no idea why
