Banshee = liquid cooled, twin cylinder, 350cc 2 stroke. Very easy to build ridiculous power out of.

Raptor 350= air cooled, single cylinder 350cc 4 stroke. Very hard to make good power out of.

Both have a completely outdated suspension setup, and the technology in the motors are outdated as well. Both can be dead reliable machines if taken care of and properly setup. The Raptor 350 would be slightly better in the trails, where as the Banshee has a huge advantage in the open areas.

Personally, I don't care for either one. The new 450's with bolt on's are as fast as your bolt on Banshee's, and the suspension setup on the 450 makes the Banshee looks like a wagon.

The Raptor 660's and 700's as mentioned are my style either. VERY tippy, and again an outdated suspension setup. If you choose to get one of these avoid the 01 660's as they are known for a weak transmissions. All 660's have issues with the one way starter bearings, L&A designs makes a good one to replace it. The 700's aren't as bad, and a YFZ450 front end will bolt right up and make a HUGE difference, as well as leaves options for tons of potential front end setups for everything from a LT MX setup to a ST XC setup.

I say if you're wanting something fun to play with, cheap parts, reliable as hail get a 400ex, LT-Z400, KFX400, or Arctic Cat DVX400. The Z/KFX/DVX are all the same machine just different plastics. They are all proven bulletproof, and tons of fun still.

If you're looking to be more serious it's hard to beat a new 450. I have a completely setup LT-R450 I'd even sell ya.
