my buddy has a rincon with 26 or 27" tires....not sure which......and he has NO prollem wheelieing..........he sits on the back of the seat and stomps it........
pretty cool to see a big utility quad wheelie.......

 

The recon is much more underpowered for its weight than the rincon and foreman. With my rancher my father would always lean off the back of it, rev it up a little and kick it into first gear. Hard on the autoclutch though, I wouldnt recommend it.
