Grip great - wet or dry. Found that the tire was a bit of a hard ride though. Had excellent wear - 22000km mostly commuting in heavy traffic!

Since i bought my cb600 Hornet 2012 it was fitted with those heavy tire, I did change it at 18000 (1500 after i bought the bike) central of the tire was almost flat but still a lot on left and right side, Im going to change it again after almost a year know and 32000ml on a clock, not bad 14000miles with it but still the same problem both sides still very good and central flat, due of taking the motorway every day but still going for the same I'm quiet happy with those

Horrible just horrible. I fitted these to the SV650S I had thinking they would be as good as the BT020's. They were not, avoid at all costs. No wet grip and barely any dry, feedback was bad then they would let go. The turn in was hard and seemed like they tried to fight it till it then flopped over. I had no confidence in these tires at all. Unfortunately they lasted 12000 miles and I had to put up with them. Buy something else!

I never read the opinions about these so my feelings are unaffected by what others think - I ride a big bandit and I ride it hard. I used 021 on the front and rear. The bike never seemed unstable or unpredictable. The grip is excellent in corners even when it's cold the rear would not slip when I throttled out. I ride aggresively and try to push the limits - never had serious situation. the front however was eaten up quite quickly - I did 3,5kkm and the sides got slick. The top of the tire was still ok.
I didn't get another set as I went for 023 instead. I would recommend 021 for heavy bikes and for riders who want a good grip in the corners and decent wear. I never go extreme in the rain so I can only tell that when you use your head while riding on wet there's little probability that these tires will surprise you.

i"ve only been riding for 2 years now,but i have done some miles,i"ve done around 45k,and it"s Bridestone every time for me,they have never let me down yet(touch wood)....Ha,they do what there meant to do and that means stick to the road and keep you on the bike,i ride very hard and i use all of the tire,i go out with a lot of experienced riders who also like to ride hard,and with Bridgestone 21s i feel just as confident as they do,and also to be honest i don"t really ride that much in the rain,but when i do i take it easy (i think) Ha and again there doing a perfect job ...............Defo recommend this tire

I bought these because of the Mixed compounds as I am forced to do a lot of motorway riding. But when I can I love the lanes. I have a pair of BT021's and although maybe I haven't pushed them to their absolute limit, I don't hang about and they have given me nothing but confidence. And just to point out, there are no chicken strips on the sides!
I recently took part in a BikeSafe day with the Met Police and it rained and rained all day. I have never pushed a bike so hard in the rain before, even very very late braking, nearly missing a turning and the tires never gave a hint of trouble.
On the motorways, well I don't hang about and the rear tire has lasted well considering, only just starting to square off, but dont let that put you off.
Overall a great allrounder that I would buy again.

I've seen a lot of reviews of these tires and they have been pretty shocking. I think this is partly down to people running the wrong pressures. The Kawasaki manual recommends 32psi front and 36psi rear. Running these pressures the tires are shocking, to the point of not wanting to ride at all. However I emailed bridgestone and they told me the pressures I should be running. This has transformed the bike beyond belief. Lots of grip wet or dry, and I'm looking to hopefully get 5500 miles out of them. I wouldn't get them again as I want to try roadsmarts, but if I bought a new bike and 021s were fitted I'd leave them on.
