The TRV is a good move if you plan to do two-up riding since it’s designed to carry a passenger (there aren’t many around like this). 500cc quads are good workers, however it depends on what you are looking for in the fun factor department when it comes to “play” time. For me power and nimbleness is important, which is why I prefer going with a big engine model. I feel you can never have “too much” power, as you will know it is there if and when you need it. In the meantime, the big brutes have no problem going slow either so it is just a matter of personal preference…
