This is the replacement for the â€œstandardâ€ Firecats. Offered in the 80 HP 500, the 600 EFI II, the new 800 (replaces the F7) and the new â€œKing Kongâ€ F-1000! All are on the Twin Spar Rigid chassis, which is a bit heavier than the Firecats. 15â€ tracks provide stability, what most impressed us is the ride and handling of the new rigid chassis. The looks might take some getting used to, the performance shouldnâ€™t. Not as â€œflickableâ€ as a Firecat, but a better trail sled for the masses. If you thought the F7 was a screamer, now you have two notches higher to choose from; yikes!
