Just mounted a 90/90-21 on my KTM 1190 Adventure R and I have to say that I'm impressed. The road grip is amazing, and as good as I've had with any dual sport tire. The cool thing is that off-road, they are pretty darn good! I've taken them on wet two track, and they been stable and solid, even in wet silt and light mud! More riding is needed to determine life, but for now, I'm happy. As a bonus, these are 3 ply tread, and should be durable in tough conditions

Well, I've returned from my cross-Canada journey and I have to say - I like these tires, a lot! They are excellent.

Almost exactly 15,000 kilometers of riding on them before the rear was completely warn out. The front actually still has some life left.

I'd highly recommend the Trekriders to anyone looking for a good 50/50 tire.

Here are some observations:

On pavement it felt as good as the Pilot Road 4 Trails I had on my Varadero - which says a lot - they're that good.

I pushed them on twisty roads, rode in wet and rain on several occasions - excellent in all conditions.

Offroad they are steady and predictable and bite into surface well. I'd say about 10% of my time on these tires was in gravel and dirt road use. Worked well in packed dirt, loose gravel and even oatmeal type much. The only place they didn't work well was loose sandy surfaces, but I'd guess that only a true knobby would work there.

It's a single compound tire and wears evenly through its life. The tires remained easy to turn in and cornered the same throughout their use right to the end.

In the end the rear tire is flat and worn across the surface and right to the bottom of the tread. The front has about 3mm left and still corners fine so could probably go at least another 1,000-1,500 kilometres.

I had a front flat (twice) on my journey and it was easy to remove the tire with simple hand tools.

At 15,000 kilometres they go on, and on, and on. If you use them primarily for dirt and gravel I'd say at about 12,000 kilometres they would stop being useful. On the pavement they were fine all the way.

If you're looking for a long-life and multi-purpose tire this is an excellent one. I've got a set of Mitas E-07 and Shinko 804/805 tires to try next to compare but I can safely say this is one of my favourite tires to date - period.

I just put these on my F800 GSA. This tires are fantastic. Which is to say, they are perfection on pavement and have enough grip to go off road. Like most people with big bikes I spend 80% of my time on road so pavement handling is important to me. That said, I would take these tires anywhere off-road in Death Valley. Would I ride for miles in sand? No...not with a 550 pound bike. Rubber is nice sticky compound. Unlikely to last as long as a K60, but will be better than a TKC 80. Just a great tire. Give it a try.

Was about to buy a set of Heidi K60's for my 2013 Suzuki Vstrom 650 to use on my Alaska ride this past summer (2017). Decided at the last minute to take a chance on these tires as a cheaper alternative - and in summary can say that I am totally satisfied with them.

I put a bit over 6K miles on the trip and this was about 65/35 slab/gravel road. Nothing too gnarly but did encounter plenty of wet pavement and some slippery gravel/muddy roads. Tires worked well in all these conditions. I was mostly concerned about tread wear but I still have a good 3 mm left on the rear and lots more on the front. I'd say another 2K miles left maybe ...

I rode with a couple other guys using TK70's and TK80's. Not surprisingly, the Avon's fell in between in terms of grip on some of the slippery stuff. (as I would have expected...)

Another reviewer thought them noisy on the highway but I can't say I noticed this over the wind noise. I will say I was extremely pleased about how relatively smooth they were on the slab. I expected much more vibration.

Net-net, I will buy these again when I replace the existing ones.

Having run the K60 Scout in the past, I found the Trekrider to be the antithesis to the K60. Where the K60 is square, and tends to be untrustworthy on wet pavement, the Trekrider has an aggressive round profile for peg grinding canyon carving on the pavement and a soft rubber compound that provides a relentless grip on the pavement in the rain. I commuted to the office in record rainfalls this spring, riding at a brisk pace, because I simply couldn't break the tires lose in the rain.

On the dirt these tires on comparable to the K60. At full pressure the Trekriders are predictable on the hardpack, gravel, and dirt. In the mud they can get loaded easy if you don't have enough wheel spin for self-cleaning, but the K60 is the same IMHO. I dropped the air pressure down a bit for the "snotty" clay trails and got even better grip.

In the longevity department, you'll get more miles out of the K60. However, the Scout tends to square off like a car tire with age and riding around the curves on the side knobs gets unnerving. The Trekrider maintains its round profile throughout its life.

This is an excellent choice for riders looking for a 50/50 tire and like to hit the twisty pavement on the way, and between the trails. This is also a great commuter tire. If you put a priority on longevity ahead of performance, you may be disappointed, but if you like to ride your adventure bike like a super moto between the trails this is the tire for you.

It's been about 3K miles with the Trekriders on a BMW R1200GS. On-road handling has been as good or better than the other DS tires I've tried from Bridgestone, Metzler, and Continental. They are the most confidence inspiring of the lot. Off-road they have been the better than anything else I've tried except TKC80s. And that includes finding myself on wilderness roads in the national forest. That said, I have not had them in deep mud or sand. They show no signs of cupping. And there is no real sign of flat-spotting, though at least half of my miles are in the mountains of VA, WV, NC, etc. Now, for the one negative...they are NOISY. Kind of a mix between the whine of an 18-wheeler and the rumble of a pickup running a mudders next to your open window. So, as much as I like them, the noise will keep me from buying another set. Bummer, as they are otherwise a winner.

Only had them for a few weeks. Its nice to be able to go from road to trail and still perform well.

BMW F800GS. I was pretty happy with these at first. The on-road grip is great and they are quiet. Offroad, the grip was also pretty darned good. However, at only 2500 miles, I had issues with the rear tire. In between the tread blocks (i.e. in the valleys), the nylon ply cords started showing through all around the tire in the middle. After another 500 miles, the nylon cords were so exposed (about the size of a dime) I felt the carcass was getting dangerously thin. There was plenty (maybe 1/2) of the actual tread left, but the plys starting to show and fray caused me to change the tire in the middle of a week long trip. Granted, most of that mileage was pretty aggressive offroad, but I feel this tire won't hold up in those conditions. I contacted Avon to see if this was an issue (construction, defect, warranty...),. but after a few days, still haven't heard back. NOT RECOMMENDED FOR EXTENDED OFFROAD USE.

I had a set of these on my BMW GSA, in less than 3000 miles I had two rear tire punctures. Once on a forest service road & once on the Freeway. My bike runs tubeless tires and I was able to plug, inflate & ride out of both situations. After the second plug I trashed the rear tire, even though it had lots of tread left. I have never ran a tire so prone to flats... wont buy another set. Too bad, as they have plenty of traction on the street & on dry gravel or dirt roads.
