Bridgestone Battlax Hypersport S22 180/45 R17 Triumph Daytona 765 3 miles November 12, 2024
Used on road and 5 track days done about 4,000 kilometres and still plenty left. In comparison to my previous tyre, Pirelli Super corsa SP’s which were done by 2,500 kilometres front and 3,500 rear. I am no expert rider so hence I haven’t scored for feedback as I wouldn’t know if it was or not! And only really use in dry weather so no wet grip score.

Michelin Road 5 180/45 R17 4,000 miles July 21, 2020
This is a soft tyre that has excellent levels of grip. Unfortunately, that's all I can say, in any positive way. These are horrible tyres when it comes to puncture resistance and longevity. The carcass is so soft, that any small nail or piece of metal will in all likelihood puncture the tyre. This does not bode well for road side fixes like tubeless plugs, nor for more permanent internal patches. I had a tubless plug spat out of this tyre that lead to a sudden deflation. Never in 30 plus years of riding and driving has this happened. When the tyre was removed and a mushroom style plug fitted, it failed to inflate. The carcass is so soft it would not vulcanise properly. The proof of this was the ease in which the tyre could be mounted on the rim with hand tools. Never again will I buy anything made by Michelin. This is a poor wearing tyre that lasted only 6000km whilst the Pilot 4s I had fitted previously lasted over 15000km. I'll stick with Japanese manufactured tyres from now on.

Bridgestone Battlax BT 012 180/45 R17 Honda 1,000 miles February 2, 2014
These tyres come fitted as standard to Honda CBR600FA. In the dry they are ok but in wet and cold they are abysmal. I came off after a slide in wet conditions, luckily not too much damage to the bike, doing around 35mph only. They are the poorest tyres I have used in over 20years and not suited to average Uk conditions. I have changed to Michelin PR3 which are excellent and the difference in wet conditions was noticeable immediately.
Do not buy and if you have these, only ride on hot summer dry days.

Bridgestone Battlax BT 023 180/45 R17 Honda CB600F FA ABS 10 miles January 2, 2013
My Honda CB600F ABS Hornet came with Michelin Pilots as original fitment - I was never happy with these so junked them early for a pair of BT021's as they suited my previous Fazer 600 very well. I've been riding for 50 years and still ride every day racking up about 8K miles a year. I have NEVER had a set of tyres so completely transform the feel of a bike (for the better). Not only was the feedback and grip massively improved, it felt like the suspension had had a major work-over. These were replaced in due course by the BT023 which improved things even more. They work as part of the suspension and comfort levels are increased as well as longevity. Grip and stability are faultless, wet or dry. Even on snow they have been the best tyre I have used.
My latest bike is an Aprilia shiver SL750 GT and I will be choosing the BT023 again.

Pirelli Diablo Rosso 180/45 R17 Ducati Monster 796 1,500 miles July 7, 2011
I couldn't agree more with honda rider who said it suddenly lets gor. I mean, when the surface gets cold, you are literally all over the place. I got them as standard on a Ducati Monster 796 and the damn thing just doesn't give you the propper grip unless the conditions are perfect ie. rough and hot and DRY!!! sufrace. The other day I was caught in a heavy rain and let me tell you that it wasn't pleaseant. I was doing about 10 mph when braking very lightly for the intersection and the bike just would't stop. I have to thant luck alone for not falling. I cannot give a propper feedback on wear though, because I've only done about 1500 miles.
Do I recommend the tires? Absolutely not!!!
