By sleeving down their 605, ATK created a 490 lineup around a belt-driven Rotax motor that included a XC (cross country), dirt tracker, and enduro models. Each bike was equipped with serious hardware – Paioli forks, Ohlins PDS shock, Excel wheels, Pro Taper bars, SuperTrapp muffler, and even billet hubs and triple clamps.
For more on this model, check out this 1998 test from Dirt Bike – they appreciated the engine and the suspension but had some complaints about the handling.
This example (VIN: 4MAT8DS83XA009682) has just 365 miles, however it spent a lot of time sitting in the original owner’s collection of 1,800(!) bikes and it does not currently run. The seller has a spare set of side covers to help with the sun faded pieces, so replace the belts in the Rotax engine, flush some fluids, and clean the carbs, and you’ll have an interesting piece of American off-road history.
