I bought my Honda VFR 1200 in June this year. The BT021s were on. At first, as it was the biggest bike I've had so far, I was overly careful at riding. As I got used to it, I picked up speed around the country lanes where I live. After the first two months, I noticed a lot of slipping and "bouncing" when I hit bumps and holes. I started to feel I was losing my skill as a rider and becoming old. Especially in the wet, I started to slow right down to go round corners and tried to stay as upright as possible. Round abouts were a nightmare. If anybody was behind me, they would be right up my back as I would be going at a snails pace. If I was riding with a group, after any corner or round about I would be a fair distance from the rider in front, so would have to speed up to get back behind them. I would have to brake earlier than usual, and gently. If I had to use my brakes harshly or quickly, I would slip to the side. The front tyre wore very unevenly and had a big dip along the right side. I suddenly realised what a GOOD and SKILLED rider I actually was, to have kept the bike upright!! I'm surprised nobody has been killed due to these tyres yet. I know we are meant to check tyres everyday, but you normally know how long a tyre is going to last, so most of us check at certain points in the tyres life. But it throws you when it's life is so short!! And it nearly throws you off the bike too!!! Very, very, VERY DANGEROUS! DO NOT BUY if you are a real biker who is often on their bike! Waste of money!

The Bat-21's were factory tires for my new 2012 Kawasaki Concours that I purchased new in 2013. I got just a little over 5K miles before the front tire started wearing in a very strange manner. The center was still intact, but to the immediate left / right of center, the tread had worn off quickly and was "greasy" looking. I had to replace the rear tire before 7K miles as it was just worn out. I check the tire pressure before riding and am not an aggressive rider by any stretch. I purchased Bat-23 as replacements trying to keep the same feel of the bike handling. I just replaced the Bat-23's with Michelin Pilot 4 GT's as I am going on a long distance trip and would have to replace the Bat-23's while out on tour. As a side note, I have my 2001 Concours running Dunlop tires and average about 10 ~ 11K per set of tires. I understand there is a weight difference between motors, but I feel the Bat-21's were not the correct tire for the 2012 Concours.

Came fitted to new Fazer 8, couldn't wait to get rid of them, front felt unsafe and wore strangely, back squared off despite varied riding, don't do A roads or motorway any more than I have too. Been riding 50 years IAM National Observer and Rospa Gold. Used to run them years ago on my 1999 R6 and loved them, so a bit of a culture shock to find them so awful.

Originally had Dunlop's on my 05 Suzy SV650 pretty good but only lasted about 6K miles. They went lumpy and caused me great concern. My local tyre fitter suggested Bridgestone Battlax BT 020's these lasted well and gave a great ride and brilliant grip. Back wore out at about 12K had a Battlax BT021 fitted worked very well. Gave a stable feel to the back and worked nicely with the BT020. About 2K miles later the front tyre wore out and I had a Battlax BT021 fitted. Totally changed the characteristics of the bike cornering is more positive and lighter, grip is brilliant wet or dry and I am very happy with this tyre.

Before I got these Bridgestone's, i had Michelin Pilot Power's. When i had those put on my Yamaha XJ6N was a different bike altogether. It would tip in with ease and hold a line incredibly well. Then i had these Bridgestone's fitted, and my motorcycling brain had to be re-calibrated to how good they are. They aren't as sporty as the Michelin's, and you can tell that by the profile and the actual compound of the rubber, but they seem to grip and pull 10 times better. I understand where people are coming from when they say the bike feels like it wants to topple over, but if you TRUST the tyres, they WILL take care of you and your machine. Get it onto the side of the tyre and these tyres will pull you out of any corner you throw them into. Yes, it feels different to other tyres. Yes, the tyre will slide if you're an anarchist with your right hand. But what tyre doesn't?! At the end of the day, tyres are all about preference. So a review on them is pretty much irrelevant because as proved by these tyres, conflicting opinions are inevitable. But i'd hate to see so many bad reviews for these fantastic tyres and Bridgestone getting a bad name when they don't deserve it whatsoever.

I have done 22k miles on an er6f using bt 021's in all weathers over approximately a two year period I have also done 20k miles on a versus 650 2010 model running bt 021's and they have never let me down these tyres are quality tyres. Thinking about trying the 023's next though. I get 10k from the back and double for the fronts. I ride every day unless there is ice on the roads.

The Bridgestone 021 is a dangerous tyre in my opinion. I've had 020's and 023's in the past and they had my full trust in them. I had a Triumph ST1050 earlier this year and was pleased to see Bridgestones on the bike when i bought it. On the first ride i couldn't figure out why the bike wouldn't go round corners, the bike would want to topple and tip into bends. And so while cautiously limpping home it won and the bike went down, they were 021's. A couple of bikes later, a CBF1000, also with 021's won't go round corners. When the wheel is on the bike the curved profile may look good, but i can see in different lights and in shadows a shamfer on each side of the profile. Just like others have said, my front has worn more on the right than the left. It's frightning, if the bars are at 10oclock or 2oclock, the bike just wants to go down. Pick anything else.

Yeah, interesting to read other reviews, as the front RHS is wearing really badly compared to the rest of the tyre. Done about 2K miles on them and looking to change already, or just turn left for the next 2K miles.

BMW GT1300GT BMW list BT021's as the recommended figment. the bike came with them on and I don't like them. They do a job, but they wear unevenly. The grip is ok and they lasted 8000 miles but the first 25% -30% of the tyres life is spent getting used to the vauge feeling when initiating a bend, exit ramp or roundabout. The last 25% -30% of the tyres life, shows that the front wears alarmingly on the off side shoulder, which doesn't add up because the rear tire bears witness to heavier wear bias on the near side. In summary, they grip ok in wet & dry, and last a while. However, the wear characteristics will make you want to change earlier. Both front and rear seem to have the same life. I'm a smooth rider, 70% motorway & 30% back roads. The softer, cornering tread area, cups badly, front & rear and the rear squares off, in such a way as to require a firm shove on the inside bar to tip her over and then a heart stopping, falling over sensation when committed. I'm looking for something else. The old BT020's were not great on my old Yamaha Fazer. If the BT 023's are any better, let me know, please.

At least in my opinion there should be one. If you are currently running BT021's I would like to hear about your experiences to ascertain if the performance I'm getting from them is an issue for them all, or if I have just got a bad one. It was already on the bike when I got it, and had really only been scrubbed in. Maybe 1000k on it or so and since then I've put another 2k on it (this is the rear). The front tyre was off the shelf when I picked the bike up (Pilot Road and it's performance is rubber magic). This tyre is dangerous. It never really inspired confidence in the first 1000km I rode the bike, but most of this was taking it easy getting the feel of a new machine. A couple of warmer rides over the 'takas it felt skittish, not letting me tip in as quickly as would be normal without starting to step out. Letting me know that pushed any harder (not that hard i might add, it was two up and you know there was no way she was letting it get too spirited) highsiding was not out of the question. Then the unthinkable happened on a relatively short city ride one morning. Completely dry road conditions through a left hand corner at maybe 40kph. A corner I have confidently taken many times far faster on a number of other bike/tyre combinations. With no warning whatsoever the back overtook the front and both bike and I were sliding off ass first across the wrong lane. If I was to offer any form of defence for it, I might say that it could have been a touch warmer but that's just rubbish. I have expected and received more from stonecold shinkos. Today the bike got it's first reasonable run since then, over the Haywards and around the inlet to see how it felt and my impression of that damn loop hasn't changed a whisker. Road conditions were premium and it is less than halfway through what I would consider should be it's usable life. At no point in my ride did I push any harder than maybe 70% of what I have been easily comfortable at on any of my other bikes. I am not a fast rider, 70% of my comfortable is probably 50% of someones who can actually ride quickly, and that only furthers my point. I'm not saying I'm a bad rider, I'm saying that the tyre behaves badly. It is extremely ill mannered at decidedly unextreme lean angles. I would go as far is to say that it is not fit for purpose. If anyone elses experience with them is anything like mine, and we were in America we would class action sue there arses off. I have ridden on Bridgestones in the past and I have never had any complaints, but I sincerely doubt when I replace it in the very near future that it will be with another Bridgestone. In fact I know it won't. I'll have a Pilot Road to match the front please because they feel like they're made of rubber, not recycled Fanta bottles. blackdog.
