Great tire only a few shortcomings
In the past I used these on a TT350 enduro. Wear is great off road and traction is good in everything except mud. However, tire was worn during the mud ride. For mud rides a MT-18 is a better choice up front. I am now replacing a set of IRC GP-1 tires on a DR 650 to see how they hold up on a dual purpose bike. Much cheaper than a set of TKCs with more bite.

Thumbs up!
I took off a new Dunlop 606 in exchange for the Pirelli MT21 and couldn't be happier. They are similar tires, but the 606 has a bad habit of washing out while riding offroad. The Pirelli changed that and seems to be a beefier tire when it comes to offroad riding. Good tire on the street too, so far.

Pirelli - MT 21 Rallycross Front Tire
A nice transition from the stock tires, I ride in sandy soil every morning when heading into work and the Pirelli's give me a smooth ride with great traction. With the tire having a medium grade rubber I try to give myself more time to slow down so as not to tear up the rubber. Great Product, will buy more when the time comes.

I have used this tire on my KTM dual-sport in numerous trips, the latest being a 4200 mile trek into Mexico and Baja. The tire performed exceptionally well; no flats, no chunking, no unexpected problems. It tracks straight and corners well in the dry conditions of Mexico. I have used it in the wet in Oregon, too, with good results; not quite as good as some but consistent. I would recommend this tire for any dual-sport adventure.

Got DOT knobs?
These tires sure don't. Mounted on a DRZ-400S. When combined with the rear, the tire does not supply equivalent traction, mostly due to the fact that the knobs are much shorter and fewer. In soft, mushy places the front washes out with the greatest of ease and does not inspire much confidence. I got better all-around performance from the stock tires on my XR650 and much better off road. Next time I will keep with the MT21 as a rear, but get something more aggressive for a front.

So far I have enjoyed these tires on my XR650L (size 90/90 21). They brake well on pavement and off-road. Much more confidence inspiring than the Dunlop 606 which I thought I enjoyed. Great tire, very aggressive knobbies. Thumbs up to Pirelli

front tire
On the highway this tire really shines. I run it on my KTM 525EXC and have about 200 miles on it. My bike has never been more stable with other tires I have tried. Off-road it's good but not great. Performance in mud is poor but manageable. So far it's just the thing I have been looking for. It's paired with the Kings KT-966 rear. If you’re mainly an off-road rider I would probably go with something more aggressive.

Great dirt tire!
I like this tire, soaks up hits and sticks well. An extra bonus--it's fairly quiet on pavement.
