Pirelli MT 21 Rallycross Rear Tire

A dual sport tire that has been depended on for a long, long time, the Pirelli MT21 features a very aggressive tread pattern that is tweaked to handle the unpredictable nature of dual sport riding. Hard wearing and yet not compromising off-road traction, the MT21 is one of the few tires out there to work in the dirt and still comfortably tolerate pavement. And as a nice bonus, it’s available in a number of sizes to fit almost every dual sport bike.

Best dual-sport tire for the rough stuff!

I've had multiple sets of these Pirelli MT 21 tires on my dual sport bikes over many years. They're aggressive, bite hard, are good in sand in the desert, and have very strong sidewalls. I ride mostly dirt, but need DOT approved tires to be highway legal. IMO these tires are as good as full-on dirt tires off-road. They're a bit more money but I'll definitely keep buying them!

F650GS

I have used these on several smaller bikes and been happy. Recently put them on my F650GS and rode the Hatfield and McCoy trail systems for 3 days. These tires did very well. On the rocky trails they held very well and I only lost one pea sized chunk off one of the center knobs. They worked very well in the lose dirt from freshly groomed trails. On the street they are very stable. So far I'm very happy with them on my F650GS.

Best all round

Hooked up way better than expected on pavement,as good as any nobby I've ever run in the dirt,only complaint,doesn't last long on rear, but I do like to use the throttle on my hopped up lc4. Already have new one waiting to replace old one!

I like it!

DR650SE, matching set. Put these tires on before a dual sport ride. Did great on wet pavement, was not trying to drag pegs, but still had no loss of confidence in traction. Saved me from going down in slick clay mud multiple times. Rear hooked up very well. Handled gravel well too. Wore a bit quickly, but great tires.

DRZ400. Great tires for street and dirt

Excellent grip in the dirt. Great feedback through the the gears and still able to slide it around. Installed on front as well. Great traction on the road as well.

Great tire for all around riding

Came on my ktm 690 r I have 4000 miles on them with maybe 1000 left. Ride it every day. TRY to stay out of the throttle. Way better then expected on road. Can all but drag pegs before sliding on pavement. A little loose in sand. No problems anywhere else other then in rain and high winds. Like I said, every day. Great hookup in almost all conditions. Will use again.

Perfect tire for the KTM 690

These come mounted on the new 690's... that should tell you something. I tried many combinations and brands on my 08 690E and the MT21's are hands down the best for DS. I have ridden the CDR and COBDR with these tires and would have no other. Plenty of miles left in a set after either of these treks. Some brands make the front end squirrely at high speed, but not the MT21. They are quite good on the road at any reasonable lean angle.

Awesome traction!

These things really bite! A little on the soft side and they take a beating on rocky trails, but man do they hook up. Second set. First set went 1,800 miles.

I have used these for extended dual sport rides for years. A few years back I enjoyed over 5,000 miles on a 140/80x18 on my Suzuki DR350se. Never had a flat and been okay with the overall performance. However, it seems that the compounds used today are not as durable as in the past, thus 4,000 is about it with the same size tire on the same bike. On remote rides it can become a huge issue- nowhere to find a replacement.

FRONT/REAR tire M21

These are mounted on a Husqvarna TR650. I cannot complain about the performance and grip of these tires off road. The on road performance is what I would expect from an aggressive dual sport knobby tire. The rear tire does not last long over the sharp desert rocks but they are inexpensive. I have about 700 miles on them currently and will at best get another 300 miles out of the rear tire. The front may last another 3000-4000 miles...looks new.

Couldn't believe the miles I got - KTM 690ER

Many people say these tires wear quickly, but I got 5,100 miles out of the front and 3,900 miles for the rear. It is probably significant to note that I'm a fairly conservative rider and never have been a tire-shredder. Works great on pavement, gravel, dirt, rocks, etc.. Hooks up well in all dry conditions. No experience in the wet stuff. On/off about 50/50. I've just spooned on another set to see whether my initial experience is repeatable.

Great Tires!

Recently spooned on a couple of these, front and rear, to ride the AZBDR. The route consisted of everything from asphalt, paved country roads, 2-track, rock gardens and skree fields. I couldn't be happier with the way the MT1s performed. They replace a Kenda 270 front and Heidenau K60 rear. Without the MT21s, there are numerous places that I would simply have gone down due to lack of traction particularly in slow sweeping 110 deg switchbacks in loose gravel/rocks.

AWESOME TIRE!

I bought these tires to replace my stock "DEATHWINGS" on my DRZ400S. Great traction off road. Works great on road as well. I ride a lot of gravel roads and these tires offer a lot more traction than my stock tires. No more uncomfortable feeling when I'm off road. Well worth the money! Cheaper than stock tires and much safer too!!

awesome

So I bought this tire used, and I trail ride and the first tire I had on were Sedona MX887's. Got tore up in 2 rides. Im talking missing knobs, so I threw on the used pirelli's and have been to the same trails the whole summer with no torn or cracked knobs, and I ride a bike known for eating up rear tires. Kx500 spins the tire no problem, and these bad boy tires held up ALL summer long! Will definitely buy a 2nd new one.
