Julien Burlington,  ON Good but not Great I bought this tire based on the 90% off-road but I must say that I am a little disappointed with the off-road traction after 150 miles on the tire. I think with my experience I would rate it 60% - 40%. If you are looking for good traction in a variety of terrains I would look elsewhere, but wears well on the street.

David G West Jordan,  UT Great Rear tire I used a set of these that were half worn during an ISDE qualifier in Idaho City on a vintage TT350 a few years back. Even half worn the rear hooked up great (front needed more grip for this race). Never chunked, always hooked up on and off road, great wear. I would use this rear tire anywhere. This tire is replacing an IRC GP-1 on a DR 650. I will consider putting one on my WR450 with a MT-18 front.

Dave Meents N Ogden,  UT Great tires Great off road tires yet still OK for pavement. IF you need good off-road tires for your dual sport bike, the Pirelli MT21's are the ones you want.

Patrick Henry Greensburg,  PA Pirelli - MT 21 Rear Tire This is a very good tire for the money. The tire performs well in anything from off road, gravel road and pavement. I have got up to 1500 miles out of one on my 640 Adventure.

Dave Gerulski Atlanta,  GA Pirelli - MT 21 Rear Tire Great tire, great price. Road 1,400 miles on dirt, mud and asphalt including a run at 85 mph down I-75 from Nashville. Tire is worn out now and will need to be replaced. I still think the durability is pretty good. It's running on an XR650R and I can spin the tire without much effort. Lot's of power. Going to order another from Motorcycle Superstore again, soon.

Ray Voluntown,  CT Pirelli MT 21 This tire hooks up! Now I see for myself why all the enduro guys rave about this tire. Rocks, roots, ledge, mud, sand...no problem!

Byron chesebro san diego,  CA Mt 21 I would highly recommend this tire for anyone with a DR 650 dual sport motorcycle that is in the dirt 50% or more. They are surprise smooth on the street for a knobby.

James Ringgold,  GA Pirelli MT21 Rallycross Review This is a great tire! I have a 2008 Husqvarna TE450 that I use primarily for off-road riding, but sometimes throw in a commute or errand running for fun. After eating the stock Pirelli rear tire up on the pavement, I needed something more durable, yet still excellent off road. This tire really does a great job. It looks like it will be making concessions to the dirt w/ the round edged knobs, but it does not at all! In soupy mud I can lift the front wheel WAY BETTER than I could the stock offroad tire! In every opportunity, gravel/rock strewn trails, muddy corners, pavement, this tire sticks great!

Phill Marion,  VA Larger Knobs than I expected Hearing all the good hype about the MT21, I bought a set for use on my DRZ 400S, and am pleased with the increase of traction the MT21 puts down as a rear in most situations, still slippery in red clay-mud, and on hard packed forest roads covered in leaves. Overall I'd say its a very nice tire that I would buy again, but the front leaves things to be desired.
