Well...not to start anything here.....but either there was a very inexperienced rider on the suzuki 450, or something else was wrong. Or the YFZ450 was not stock at all. Between a modded lt-r450 and a stock yfz450....the yfz does not have a chance.
Between you banshee and the lt-r450......unless your banshee has some good porting, pipes, etc and very well tuned......the modded suzuki will usually still win.
Believe me when I say I am not bagging on the YFZ450....they are killer bikes and can be made VERY fast. But in stock trim, they will not touch a modded lt-r450. I had the cheapest mods available on my lt-r450 "pull the spark arestor, cherry bomb module, pro design filter kit", and had no problem keeping up and or beating most of my buddies ported, piped, carbed, banshees. And unless any yfz450's I raced were piped, jetted, intake, cdi......they wouldnt have a chance.
Like I said.....I'm not trying to start anything here.....and everyone on here know I am a banshee man.....but you cannot mess with a good running, even slighty modded lt-r450.
