What was previously known as the IQ 550 is now, for 2014, the Indy 550.
The IQ 550 fan was a credible fan cooler, however, if you could drop more than 25 pounds from a sled and get better handling, better ride and improved performance – wouldn’t you?
Polaris took its Indy 600/800 chassis, a hybrid variant of the Pro-Ride RUSH platform, and slid its reliable 550cc fan mill inside.
The new Indy chassis employs what appears to be the same 121-inch coupled, dual shock, torsion spring skidframe used in the IQ. At the front, the uber-light cast bulkhead and all associated bodywork and front suspension are RUSH.
A major change is the use of a new CVTech PowerBloc, rubber-puck-style primary clutch and a new Invance secondary.
Yes, these appear to be cost-down items but the performance here is not just good, it’s doggone impressive!
Last spring, at six thousand feet elevation, the Indy 550 would wind up to an indicated 70-per without missing a beat.
Acceleration and backshifts were strong and the light feel of the chassis was undeniably a big step up from the heavier IQ platform.
If you want more flotation, the same sled comes with a 144 x 1.35 Cobra. It’s called, not surprisingly, the Indy 550 144.
The skid is dual shock, uncoupled and provides stupid flotation for an already featherweight sled.
