Which of these is over the fastest and will give me the least trouble as far as taking care of it goes, also any problems you know about any of these please let me know also. I plan on doing a little trail riding but I will do drag racing for sure. I really like the Quazilla but im not sure if a late 80's-early90's quad will be as dependable as i need it to be. what do you guys think? Thanks

 

The machine that will give you the least amount of trouble would have to be a four stroke(yfz 450). The ZIlla was the fastest production quad ever built(87-90). The Banshee is probably second.

 

Yfz is faster then a banshee.. just my 2 cents i dunnp if you would count the storm atv porduction if so the zilla's is not yhe fastest

 

yfz or banshee is probally your most reliable and easy riding but if you want to have good torque and power go with the quadzilla I ride a banshee with a trinity stage iv and my quadzilla will spank it at the dunes but my quadzilla aint stock either so stock for stock I would go probally with the shee thats just my opinion.

 

Well, my 87 QZ has been completely restored.....Name any part on it and it has been replaced, repaired, or repainted, and all I do is trail ride with it. We have a few pits to climb, but nothing to serious. It does good with the powervalve, although you need to wind it up every now and then to keep the plug from fouling. I have AT triple rates up front, and a rebuilt stock shock on the rear, and it handles really well on fast and slower trails, although the ground clearance isn't spectacular (with 21" Mudsharks), but no worse than the other 2 quads you mentioned.

So far I've run into a bolt-on Shee, and a Vito's, but neither could hang with me. I haven't run a new 450 yet, but I'm not going to be worried if I do. The guy I bought it from was getting 96mph out of it at the ice drags (not sure of the distance, but my boss's 03 ZRT sled would get just about 100), so its pretty fast.

I haven't had any touble with mine, and I change the gearcase oil often, and clean and re-grease all the suspension and wheel bearings once a year.

Oh yeah, I can also let it lug down in 3rd gear to the point of almost stalling, crack the throttle and send the front end skyward with out tugging on the bars.....try that on a Banshee....

Arctic Cat did not make a 03 ZRT. Cat stoped makeing the ZRT 800 in 2001 and they stoped makeing the ZRT 600 in 2002.
And as for the Quads I would have to say the YFZ 450 would give you the least trouble and the Quadzilla is the fastest.
My Buddy has a Mod YFZ 450 and it has the power & Speed of a Piped & Air filter & Rejeted Banshee

 

I think fmf is right but I think artic cat was dumb stop making the triple and specialy the thundercat big mistake.

 

My dad has a 01 Mod ZRT 600 LE and I have a 04 Mod F6 Sno Pro. Yes it was a Big mistake that they stoped makeing the triples.

 

All I know is its big, fast, green, and an 03...Although its not a Firecat...

 

I might be a ZR 900
