I'm toying with the idea of a T660 for my wife......
She now rides an F5 and likes it.... with that being said our son likes it a little more than she and rides it VERY well (he's 12 and has a 92 EXT 550 EFI and wants a new sled with a better rear suspension) so the problem is this...... when we all three ride together she ends up on the 92 EXT and he rides the Firecat......
Personally I prefer a ZR chassis over the Firecat and I honestly feel she rides better/faster on a ZR chassis..... our son rides the F Cat like it's his KTM dirtbike (standing up and looking for launch pads) and there aren't any issues with him on that sled...Many have said he rides better than most adults.

Are there any "issues" with the T660 as far as motor/suspension chassis issues???
I am thinking if I did get her a good used one I'd like to either install a 1.25 track on it or possibly install a 136x1.25" track like I did to my ZR 900....... WAY better ride with no push in the corners at all..... we no-longer run studs in our sleds so a 1.25 or 1.375 would be the answer.

Thanks in advance.

My wife has been on a 04' 660 turbo touring since it was new, 8000 plus miles on it now, pretty much trouble free, I've changed the engine oil every season, chain case oil every season, and all bearings once (just because). She loves it, I ride an 02' non-turbo turbo touring with with slightly more milage, I've done the same maint. stuff to it, we both came off from hot 2-strokes, (now we have 2 kids, needed room for them to ride along). I can't say anything bad about the 660's. Some people complain about "turbo lag", my wife has yet to say anything about it, I just see the smirk on her face as see flys by me....We ride alot and love the 660's.......My folks just jumped ship from Polaris 4 strokes to the 660LE's....I'm the only one with a "slower" sled now, HMMMMM maybe I should do something about that.....hey honey, can we go the Cat shop this............................................

I have one for sale if you are looking 05 turbo touring or may have an 04 if my brother makes up his mine to buy this one n sell his.

I have about 400 miles on mine n love it. Smooth ride, no smell, good gas mileage and plenty of get up n go. Only issues I have had was the battery n gas gauge, float arm fell off.
