I jus got myself a kx85 on minimoto 12" wheels. I bought the bike with the wheels but everyone else at the track has 16" or 17" wheels. I am curious to know what the opinions are for the pros n cons of each set-up. Thanks in advance
Since it's already set up on 12s, ride it and see how it goes. You're either going to love it or hate it, it's just a personal preference thing. I have ridden both and prefer 17s. The 12s can be too "twitchy" for some and the ground clearance can be a problem (pegs/ boots dragging). The general idea is that 12s may be "better" on a tight, technical track, where the 17s may be "better" at fast, flowing tracks.
I love 12's! You should really try 12's first. Especially using PMT's. You will be surprised on how hard you can push.
I have 12 pmt streets on right now. I've ridden with them and haven't had any issues I was just curious to any differences
You save a little $$$ using 12's vs 17's. From the riding I do and the guys I ride with (depending on the track) the 12" last longer than the 17" . Wheels are cheaper too. The 17'' are more stable but the 12" are way more fun.
