Pirelli MT21 Rallycross Tires 4.7 5 9 9
Trans-America Trail torture tested - approved! This tire is phenomenal as a front and rear though I'm a little more enthusiastic about the front. These tires saw air temperatures ranging from 38F to 115F and ate it all up. The previous setup on my WR250R was a Scorpion Pro FIM front and an MT-43 trials rear. The MT-21 front tire gives 90% of the off road traction as the pro FIM but doesn't get chewed up on the pavement. The front tire is currently at 75% after about 3000 miles of 75% dirt 25% street riding. It continues to perform like new under all conditions. Lets face it, the rear tire doesn't hook up exactly like the old trials tire running 8 psi but it's a lot more fun and it never kicks out and surprises you. It's better than the trials in mud that's for sure, and so the rear hasn't held up as well as the front due to throttle wringing and has maybe 25% tread life left. In its current state I'd feel confident in everything except deep sand. I will probably still purchase the rear again since it hasn't let me down from single track to interstate. No problems on crazy canyon switchbacks whether there's pavement or not - dips into banked turns ok. Top speed I saw on pavement was an indicated 87 MPH, no undue vibrations. From Oklahoma to California I had zero problems - dirt, mud, gravel, sand, DEEP sand, rocks, scree, boulder fields... all dominated with the help of the MT-21. All crashes due only to user error not weak tires. No pinch flats running 15 psi front 16 psi rear in all conditions, heavy duty Michelin tubes. I do recommend running these in the 15-18 psi range. I will probably run these tires again even if I expect primarily street and gravel roads. Friend has one on the front on his KLR and also loves it. Hats off to the revzilla team for getting this tire to me out on the trail exactly where and when I needed it. A phone call to ZLA placed from the middle of no where got all the details worked out.

Great all around tire, wears out quickly on-road. This is mostly an off-road tire so I can see where it would wear quickly on road. I ride mostly off road when I can and this tire works great for that. I like to have fresh tires and at this price point I don't mind replacing tires often. I use them on my KTM 690. June 15, 2015
Great on and off road When I bought my bike it was used with worn out tires when I put the mt21s on it was like another bike November 3, 2014
First MT21 set purchased. But will buy again! Bought a set of these tires for LA-Barstow To Vegas. And to say, I am happy I did. Tires held up great! Had 4 flat tires in the group, but like I stated out on the trail, "You do not see me changing tubes." Yes I ran the whole ride, with no flats. all 7 of us road KTM 500 EXC' s. And 3 others got flats. I did not! I ran them at 17-18lbs. Felt great in all conditions we crossed. I will buy the next set when needed. I am happy I jumped over to them! December 1, 2014
Fun tire This tire came stock on my 2014 KTM 690 Enduro R. When it was new (< 300 road miles) it stuck like glue in slightly moist dirt, even if I didn't air it down below road pressure (26-32psi). I would say it hooks up substantially better than comparable dual-sport tires and it lives up to its 90/10 dirt/road claim. It also performs quite well on the road *in good conditions*. The tire is quite soft and sticks to the pavement very well for such a knobby tire - I found myself scraping footpegs when leaning over very gingerly in smooth, dry and friendly-cambered twisties. That said, the contact patch is quite small. Therefore, if the road is wet, cracked and/or rough and you happen to pass over a small imperfection while leaned over (a painted line, a small crack, etc.), the tire will start to slip out from underneath you. With the rear, this isn't a big deal - but it's pretty scary when it happens on the front! This would make a *terrible* commuting or "adventuring" (highway miles) tire. It howls at 40mph+ and it just doesn't last very long on the road. I have almost 1,000mi on these tires, roughly 70% of which were on pavement and 30% on dirt, gravel, mud and sand. I have only run them at as low as 22psi once, and it was for about 10 miles of technical offroad trail-riding - they work so well at stock pressures that I haven't bothered airing them down since. It comes as no surprise to me that the rear is looking very spent indeed, and it doesn't snap in the dirt like it used to. Even for casual trail use, it will beg replacing sometime in the next 500mi. However, for the moment it's still very useable on-road and off as long as you're not in a crazed race-fed hurry. Believe it or not, I actually had some fun in the soft sand today, where guys with more road-oriented dual-sport tires were getting stuck and frustrated. The front looks OK to go another 1,000mi. So this is a fun tire, to take out on sunny days on nice roads and on moderately challenging trails. Don't expect to commute economically on it and don't expect to win any serious races - and it won't let you down. June 15, 2014
Good for it's purpose This tire comes standard on the KTM 690 Enduro R. It's a good 90/10 tire. It will come as no surprise that this tire has terrific manners off-road. It's nearly as good in mud as a full-on dirt tire. It's a little skittish in sand and off-camber situations, but that could be because of the 690's additional weight. I'll know better once I've compared some other tires on the bike. It has better road manners than it's tread pattern would imply. It's a neat trick, but it comes at a price; the softer rubber doesn't fare well on slab. My tire is nearing the end of it's life after just 2000 miles. The front tire (another MT21) is hardly worn. Granted, I spent more time on road than off. If your dedicated use is TRULY 90/10, then this tire might be a great option. I may continue with the MT21 on the front, but out back I'm gonna explore other options--probably the D908 or the Heidendau 60. June 8, 2014
Great off road dual sport tire This went on my DR650. It rides well on and off road. I won't hesitate to run another one. I paired it with a D606 on the rear and it's a great combo. After 2500 miles the rear is shot, but this front is only about 2/3 worn. It's starting to cup/feather so I may flip it around an see if I can squeeze some more life out of it. If not, oh we'll, for the price I don't feel it owes me anything. June 4, 2014
Great tire so far I have had this tire on my BMW F800GS for about a month now and a few hundred miles. On the pavement the tire works good, in the loose rocks it hooks up nicely, the mud it grips well. The wet grass it was a little loose but eventually digs in nicely. So far it has been a great tire.
