3. Earlier we said the first thing we'd do to any fuel-injected snowbike is
run a Raze Wingman kit. Well, the second thing we would do is the Raze
coolant-heated handlebars. Its a must-have, otherwise you're stopping and heat-
ing your hands on the exhaust every 10-15 minutes. The Raze heated handlebars
are awesome because they don't use any of battery power––you can save that for
starting the engine. They are efficient and they are hot.

2. We started our KTM 450 XC-F
builds with a Thumper Racing 490
big bore kit, and that was awesome
because it gave greater diameter to
the piston, but kept the stroke the
same. The bike would still rev and be-
haved just like it would as a stock KTM
450. That was really cool, because
you keep the same throttle response
and high revving engine but at with
the perks of a 500. It had a lot more
torque all through the power range. It
just rain so well. It was one the most
powerful naturally-aspirated bikes I
we've ridden. And in many ways it was
much more fun to ride than a turbo-
charged bike because of the instant
response. You always knew what it was
gonna do. It liked to rev high and be
ridden hard.
