I wouldn't say a stonger engine. Those 99 440 Edge racer modles had pretty hi-strung engines. I think they turn 8800-8900rpm?? I really havn't heard good things about them on the trail. Not to mention they were weak in the body in spots. There are updates for them tho. The 00 XC was better I think..detuned back some. Buddy has one, fun sled. Still can't catch me in 660ft tho Originally posted by madcow
[br]the 99 in the edge chassis is a lot stronger motor. can pull a lot more clutching. the ride is unbelievable upgrade.
