My garage is full at the moment. Really full. I’ve got projects piled on projects, and at the top of my to-do list for January was prepping the XR250R for a frozen flat-track. This proved both the easiest and most difficult conversion of this whole Six Ways to Sunday adventure. Taking the one motorcycle out to compete in cross country, motocross, flat track, road racing, trials, and finally on ice requires a lot of time in the garage. So much that I was getting burnt out. Luckily this final conversion only required three items: studded tires, over fenders, and a tether kill-switch. Simple, right? I thought so, too.
The refrigerator inside my home holds no adult beverages, for two reasons: There are too many tasty leftovers packing the shelves, and I found myself gaining a little belly in the last few years. Therefore, I make access to unhealthy drinks marginally less convenient by storing them in the garage. With each trip out to the garage fridge since I returned from the Barber Vintage Festival in October, I saw the XR on the lift, ready to get a service and in need of parts. It wasn’t cold yet, however, and the thought of ice strong enough to support a motorcycle was comical.
I’ll get to that when the weather turns.
Of all the hard-to-find parts or creative solutions demanded by the XR250R, tires have never been an issue. It runs pretty standard sizes, at least for a vintage machine: a 21-inch front and a 18-inch rear. (Modern off-road machines are typically fitted with 19-inch rear hoops.) I figured it wouldn’t be too hard to find a set of studded tires ready to mount. I didn’t even need the nicest tires, just ones that would get me out on track. Surely a used set would be available for reasonable money.
Nope.
I thought I struck gold when I ventured to an ice racing event to spectate and found an 18-inch rear tire. Bought the set on the spot for cash. Only when I got home and attempted to mount them did I discover just how dumb I was. The pair I had bought in such haste were an 18-inch rear and 19-inch front—like an odd flat-track setup. I put the tools down and walked to the fridge, grabbing a koozie from the catch-all shelf on the way.
Then it hit me like a bright yellow 1933 Ford pickup. Just call Jeff.
You’d be forgiven for thinking that prepping a set of ice-worthy motorcycle tires involves nothing more than a drill and a bag of screws. Problem is, a lot of physics is involved. The slight angles placed on the screws have a critical impact on how the bike handles and puts down power. We aren’t talking sheetmetal screws, either. There are specially made screws for ice racing, including ones specific to the event I plan to run. Since the race I’m attending is an AMA (American Motorcyclist Association) sanctioned event, the screws can have heads no taller than a quarter-inch. I could go about studding my own tires, but it really didn’t make sense if I wanted to get on the ice this year. So I picked up the phone to one of the best ice-tire guys in the U.S.: Jeff Fredette.
The tether kill switch is borrowed from a snowmobile and shuts the engine down should I become unceremoniously disconnected from the bike mid-race. It’s a two-wire install that replaces the push-button kill switch already on the handlebars.
