    • Road manners are good, but off-road is where they shine.

Good street manners and awesome off-road. We tackled everything from deep mud, slick hill climbs, gravel and rocks. They appear to have taken cues from the Dunlop 606's and are virtually identical side by side, with slight differences. I've only got one ride on then so far, but I'm confident they'll serve me well. They were far easier to mount than the Dunlop TrailMax that I took off, and the rear is significantly lighter. The sidewalls are stiff since they're a bias ply, but they also run cooler thana radial. I'm extremely satisfied. They transformed my Tenere when the terrain is less forgiving. ... show more

    • BEST TIRE FOR THE MONEY HANDS DOWN!
Size: 90/90-21 (54R)/130/90-18 (69R)
If you are dual sporting, you cannot beat the Tusk DSport. They are tough and durable. Unlike gummy dirt tires, they can take on long stretches of highway for thousands of miles without wearing down the lugs. They have incredible traction in all conditions. Great on dirt, trails, single track, and even rocky climbs! They are ok in the sand, but if you have a heavy bike like my KLR650 (over 500lbs when loaded) they will get you around but not gracefully. The best thing is that they perform well on the roads. Yes, they have a little wiggle when brand new, but it's not bad, and once you're used to it you can lean into the turns just like a sport bike. I have DSports on 4 different bikes. My WR450F, DR350S, and 2 KLR650s. I can't say enough good things about them. The performance for the cost pretty much makes other tires obsolete. ... show more

    • Great Traction
Size: 90/90-21 (54R)/130/90-17 (68R)
Had these on for around 1k miles so far on my KLR 650. Traction is fantastic offroad in gravel/dirt/mud/grass not too sure about rocky terrain, its done fine for the few small rocky patches I've ridden, but haven't got to test that much. Beware, I have been told they kick up a lot of rocks for anyone riding behind. They do surprisingly well on the road too. I came from street bikes and still corner fairly hard on my klr, obviously these aren't as good as a street tire, but WAY better than I expected. I imagine I will be buying these again barring any unforseen issues that haven't shown themselves yet ... show more

    • Very good tires
Size: 90/90-21 (54R)/120/90-18 (65R)
Review Image by Amazon Customer
Good set of tires. Installed them myself with tire spoons. Was a little tough but not my first set to install it does take a little know how. Was worried about balancing them but I installed them with the yellow dot on the tire to the valve stem where it belongs. The test ride was great with much improved traction and they were balanced out very nice as they were. No additional weights needed. Rode very well on paved road at high speed 70+ mph. The traction on gravel roads very good not afraid to turn or lean the bike in fear of sliding as with the stock tires. They were installed on a 2024 Honda CRF300l. Did not notice any less or more power due to very slight size difference from stock. Made the bike look more aggressive. Price was good to me. ... show more

    • KLX300 90/90-21 and 120/90-18. Great tire for the price! Stiff sidewall, spooned on just fine!

So far so good. I see why people complain about the front tire, but it's a pretty aggressive knob and they are stiff so it will "hunt" on pavement a little at lower speeds, but noise at speed is fine. Offroad grip is good even without airing down a lot. I have more testing to do with them offroad at lower pressures, but for the price. They weren't as hard to mount as people say, if anything they were a little easier. ... show more

    • Killer tires, for a good price!
Size: 90/90-21 (54R)/120/90-18 (65R)
Great tires, but terrible balance. It took like 3 big weights on the front tire to get it close. I ran out of weights for the back, but they're considerably better than the last set I had on there once I got them balanced. If you have bead locks, you'll obviously have a lot more to counter, so I can't blame it squarely on the tires. These do great on pavement and all the way up in the 80mpg range without a huge amount of fuss. They knobbies, so they'll buzz a bit. But it's not bad. I'll repeat it again though, you really, really want to balance these things out of you want to go over 45-55mph, or else you'll rattle your teeth out! These tires do excellent off-road even after q couple thousand miles. I haven't worn them out yet, so pretty darn good so far! ... show more

I got these tires for my dual sport with off-roading in mind, and that's exactly how I use them. I ride in some very rocky areas and could swear I'm going to have a pinch flat some times, but these tires are great. I have run them with as little as 15psi at times and they hook up very well.. sometimes they slide on wet rocks, but I think most tires will do that. Hill climbs in rocks and packed dirt - you could pull a wheelie all the way up and keep traction on that back tire. I installed them myself, and they were pretty tough to get on the rims, but I kept working and finally got them. On the road they are, well they are knobbies.. and you will feel that. They hum on smooth paved roads, and feel a bit uneasy at first on the roads, but now I'm leaning into turns, and they are fine. In deep puddles and thick mud, they find their grip and get you through.. I was once in knee deep water with soft mud on the bottom and they pulled me right through it. So I do recommend these tires for dual sport bikes if your biased towards off roading. If you ride the roads mostly, you won't need these, and you'd be better off with something a little smoother. ... show more
