Re: the trx 90
First off, I am not bashing the fact that the TRX is reliable. It is. Like you said, you bought a "Polaris". It retails for almost the same as the TRX, but, does'nt have the same reliability as alot of other quads. The closer that you really look at the Kaseas, the more that you will see that it is a high quality built machine. Once you take an engine beyond 90cc, it ceases to be a 90.
A little about my background; I have been a motorcycle mechanic for over 25 years, raced on a national team, have been involved in R&D, and, still build race bikes & quads. I still ride & race....even at 43 years young. In fact, I earned 1st overall in the ARK-MO Summer Nationals Motocross Series , racing a Kasea Skyhawk 150cc quad. The only modifications to the engine were a Big Gun header & silencer. I had no mechanical breakdowns in the last two years of racing this quad. In fact, The original clutch plates are still in the quad (and I have constantly abused them) and, they still don't slip !! Do that with any other quad on the market. (RETRACTION: I did blow the seal in the rear shock.) I have tested & abused Kasea quads. They are like a Timex watch....."they take a licking & keep on ticking "
