This is a replacement tire for my 2012 WR450F. Original was Geomax 51. First ride was a mix of hardpack and mud. Seems to work good, but had a few slips in the corners. We'll see how long it will last.
Paired with a matching rear on my KTM 690 after wearing out the excellent stock MT21 tires. My first impressions were on-road and the tire was an absolute mess. Any input to the bars over 40mph caused the bars to start a minor tank-slapper. Off road the tire seemed fine (no better or worse then the stock tires). I took it off after less than 200-miles. I replaced it with a more street-oriented tire and the wobble went completely away.
I bought these tires in order to make my Yamaha WR450F street legal. I have ridden multiple times in mud, dirt and sand and the tires work very well. I cannot speak to their on road performance since I am still waiting on the DMV paperwork required for my tag.
Geo MX32 is a great tire, but you should ONLY ride on soft dirt, or snow, or sand. I thought I would need the traction for soft terrain, but I made the mistake of not considering where I ride. When I take it on gravel or hard dirt, the tread wears like crazy. A much better choice for average off road terrain is the Geo MX52. Still is a wonderful tire, and every aspect of handling has improved.
