I've made 8000 km, at least 2500 on winding roads and my opinion is that they are very nice tires.
Pros: fluid bend in motion, and apparently good in changing the direction.
Central part is very tough and lasts a lot!!
Cons: the front tire wears out much more than the rear one. The
consumption ratio especially on the lateral part is 2 to 1. The
lateral part of the rear tire is quite good.

I have used these on the track on a cold, but sunny October day and they were producing enough grip to get my knee down. Generally in warm, dry conditions they will suit most road riding. However it's not to say I haven't had them slip even on a good day. But, if you fancy scaring yourself ringing, just add water, and not a lot; a terrible tire in the rain and even damp conditions. Slips when accelerating even when upright, requiring progressive acceleration and cornering just stops being fun! I wouldn't look to purchase these.

My R1 gets used for all sorts but mostly spirited riding and the 016 does a good job in hot dry weather however I live in the UK where hot days are few and far between ... Wet grip is ok for the first 3rd of the tire use but after that it is shocking "bambi on ice" is an oft used term but is fitting. Even at sensible wet speed on the motor way confidence in the front and rear is lacking and its a delight to get off the bike for all the wrong reasons.

Wear is about right (~3000miles per rear) for a tire this sporty but a few motorway trips = sqauring off which is alarming and this is a tire that generates a nervous rear shortly after.

Z1000sx 12000 miles a year.
These were the stock tires on the bike from new. On a hot dry day these tires had a lot of grip. The sides were very sticky and would shred right to the edge, I had the bike very low on the and never felt worried.

In the wet and cold they were pretty awful though I think.
They lasted 3500 miles, and I've now got bt 023 my favourite tire for commuting.

These tires are good for summer/weekend riders but not for commuting all year round.

I've also offered a review on the BT014 for comparison which is worth reading.
This review is really a warning about these tires.
For an 02 R1 in British weather, don't get these.

They take ages to warm up, scooters were overtaking me in the morning.
They slip in the dry on a straight road from a low speed average brake eg the 40 yards to the end of my road, braked at 20mph, the damn things slid 10m on a bone dry summer's morning. Useless.
In the wet, God, they;re dangerous. Went on a police rider assessment course with a 200 mile scrubbed in set, adopting their style of riding. It was terrifying. Had me in the hedge at one stage. The police rider asked me if I'd feel more comfy on a different bike. Swapped back to my style and he said it was a different person riding, but apart from all that we came up to some lights in town, heaving down rain, pulled the brakes gently enough, straight slide 12 yards. Had to use my feet to lend stability.
On the motorway no feedback on bends, stepped out at the rear a good handful of times.

I had to become a Jesus grandad (see the future, ride gently) of a rider. I took the bike on tour to Germany just to use up the tires on the motorway for which they were OK through 10 hours riding. When I got to Germany the following days, without the motorway warm up, the tires gave me no confidence through lots and lots of bendy back roads. Anyway when I got home I changed them back to my beloved BT014s (much more grip, feedback and low angle cornering).

Please don't buy these for your R1 for your health's sake. I'm amazed they;'re from the same manufacturer as the 014s really.

I think they are BT014s on the outer 2 edges and 021s in the middle 3 bands. That would explain all the slips. BT021s (which I've also tried, well I was skint and they were on offer) aren't suitable for an R1 at all.

i have only got 3500 miles out of these.. i didn't find them that great the grip was good in the dry but in the wet/damp it was almost non exetance causing alot of rear wheel spin causing the bike to step out some times espeshaly after heavy pull aways..

I've used three sets of these on my 08 gixxer 600. They average out at about 9000km per set. The rear wears out in the centre whilst the front goes out on the shoulders.
I ride lots of highway trips - usually a minimum of 70 - 100km at a time. I do the odd track day as well.
We have fairly mild weather here (New Zealand - Waikato region) so I have noticed no problems with warm-up.
I have learned to trust these tires totally and have yet to have them let me down. The only time the back stepped out was when, after a service, they had been over-inflated (48psi). I usually run 40 rear and about 36 front. Track day they drop to 35 each. These pressures seem to work happily enough.
Wet grip I am less sure of althoug last track day was really wet and they held up just fine. Mind you, I took it easy.
I wouldn't trust them on wet shiny seal though or on wet white lines - I tried them out in a straight line once and they broke free really easily. But then I'd expect that from any tire.
Good treads IMO.

These tires make you think too much which is not always a bad thing. However I will explain why these tires are not good unless you a riding hard on a hot day or on the track.
The pro's.
High speed stability fantastic good grip levels and feel.
Wet grip is quite adequate for a supersport tire.
Good dry grip levels when the tire is warm to hot, the rear tire is especially grippy.
The Con's.
poor wear rates compared to competitors tires, front tire gets chewed up easy and the rear will wear down in the centre too quickly. However it is possible to get over 2,000 miles of hardish riding on these which isnt terrible.
The grip is only in a narrow temperature range, too cold they have very poor grip especially the front is extremly slippy when not very warm at lest. Too hot and again they become slippy again. This is why I would not recommend these tires. Say you got the tryes warm on a warmish day then you got stuck in traffic or slowed through a village or something or was on the motorway for a while. In this time the tires are too cool again and the grip is not there. I find the grip is never there when you need it only when you start riding hard for longperiods does the tire become good and then if it gets too hot...annoying. Will be getting Dunlop sportmax D209's next time.

Excellent Tires for racing as well as touring and allows you to push the bike to its limits.

I think i will get 1700miles great tires,shame rear will still have 3/400 left on it but front shot,still loads better than BSB's only got 1000 and front was gone at 800 very poor when cold,great if smooth road and hot

I Live near Chicago and see all the different weather issues mother nature loves to throw at us. I love to ride for miles for no reason but in the same light, I adore a good track. I need something that has good mileage with the ability to get nasty for a few days at a time.

With this odd marriage of Mileage and track readiness there is a compromise, it comes 'warm up time'. During the early season especially one must take caution to ride a good 5 miles before leaning and really getting on the throttle hard. If you keep patient then the tire will def. reward you. Don't take the warm up time lightly.

Ive ridden on these for 14 months now, with 9000 miles on them (I never did a burnout or get crazy squirrelly on em). and 3 days of track days in the fall (so it wasn't crazy hot). Its more than I could ever expect to see from a tire with such a diverse ability.

They are quite cheap compared to many others out there as well. And it doesn't hurt to hear that Bridgestone is the only tire used in MotoGP to date. They have to be doing something right to make the GP riders say Michelin tires were a disadvantage vs. the Bridgestones....

If your an occasional canyon or track rider that loves long rides and watches their money, than this is the only tire you should look for. Just be patient before you rock the throttle...

Recomendo estes pneus para quem tiver uma condução normal, quem quiser dar um uso desportivo este pneu nao segura como devia segurar.
Eu não o voltarei usar.
