I have been super excited about this bike for a while. We saw images of the new engine a few months ago and could only assume that a chassis was on the way. Well, CW got the exclusive look at the bike in it's prototype form at the Minn fortress of solitude. The rules and regs for Dirt Tracking are pretty lax, if not non-existent, so Indian was able to start with a clean slate in dev'ing their dirt tracker. They took notes on what was working and what racers would change if given the opportunity. Indian looked to AMA Racer, Jared Mees, for input on his ideal setup. He is a multi-time champion on the dirt oval and quite capable to give the Indian engineering team the direction they need to make this bike come to life. The plan has been to create five prototypes and several spares. I can only assume that each one of these prototypes is slightly different so that they can hone in on the perfect setup. The frame sits at a neutral 55-inch wheelbase and offers adjustment of 7/8 of an inch front and rear. While this is not anything different than the other bikes in the field, where the difference comes is in the ultra-light powerplant. The FTR750 engine weighs just 106 pounds and is compact enough to be placed in multiple positions in the frame to optimize performance on track. This will be the first steel tube chassis to come out of the Medina think tank. I assume that the relatively small diameter tubing is chromoly to provide strength and easy track-side modification and repair with common welding equipment. The only thing that makes me doubt the chromoly is the mention of the need for flex out on track. The more narrow gauge steel could accommodate the desired flex characteristics though. Tech Specs of the Chassis are as follows: Steering-head Angle: 25 degrees w/ headstock cups allowing 2 degrees of adjustment Trail: 3.9 inches (99mm) w/ 53mm fork tube offset from the steering axis & more adjustment available w/ fork crowns Crankshaft: 25.5 inches behind front axle at full droop (2 inches ahead of wheelbase mid-point) Tank Capacity: 2.2 Carbon Tank (2 pieces using the Scout tank as a reference point for design) Injector: 1 per cylinder (sourced from the production Scout) Fuel Pump: Operates at 60 psi (sourced from the production Scout) Air Intake: Vertical Downdraft with High Surface Area Filter Chassis Torsional Stiffness: 572 pound-feet per degree Lateral Stiffness: 292 pounds per millimeter Radiator Core: 6 x 8.5 inches The frame supports multiple head tube support loops. Two run the span from the seat to the head tube above the tank and two below. This will provide protection for the carbon tank in the event of an accident out on track. The frame did resemble some of the popular aftermarket frames available on the market in keeping with the Polaris approach of not reinventing the wheel whenever possible. The frame features only the necessary supports and tubing to keep the wight of the chassis down. The seat frame offers both a very minimal appearance, but also many different mounting points allowing the rider to customize the riding position and the weight distribution. The exhaust is mounted on the left side of the bike and composed of 20-gauge 304 stainless steel starting with a diameter of 1.75 inches and expanding to 2.25 inches. Minimal baffling leads the V-twin two stroke engine to have a "very loud" exhaust note. The FTR750 retains the clean look of the Scout engine by forgoing the superfluous cooling fins. Being a water cooled engine, the cooling of engine components is handled by the radiator hanging forward of the frame downtubes and aft of the fork stanchions. The FTR750 is rated at 109 horsepower, rendering a little over 1 horsepower for every pound the engine weighs. That is huge! I am excited to see this thing in action and I can only assume that they are going to have something ready for the Flat Track races scheduled for this year's Sturgis Rally. Hopefully we have some members up there to report on this for us!
