I use the GP 211 treaded on my Gixxer. Love them. 212 doesn't come in a 180

PB Slick Tyre Test

I read that article with interest but noted that they didn't include the Bridgestone V02 and were also testing the SC3 compound Pirelli which hardly anyone ever uses. What surprised me most was that they also ran the Racetec RR K2 front tyre outside of Metzeler's own recommended pressure ranges. Unsurprisingly they then commented that using a lower front pressure would have been more beneficial! The tyre supplier really should have known better. Other than that it's good to read a track tyre article for a change as most tyre tests are more road biased.
 
I've been racing on michelin for 2 year and those pressures seem way too high to me. Although they're the experts so they will be right

Track Tyre Pressures

Having looked at the tyre pressures they do seem somewhat at odds with the manufacturer recommended track pressures. It's not a great advert for the tyre supplier who has clearly performed a rather inconsistent job.
 
Yeah I thought the same. I'm racing on the metz and running 32 27 which seems to work. Would depend on what bike it was tested on also I suppose. The beemer tends to obliterate k2 rears when its warm. My only gripe with the metz is the lack of compounds compared tot he SC
 
Metzeler Racetec RR

I also use Metzeler and normally run hot pressures of 32F and 27/26R which are well within the recommended pressure ranges. I definitely agree and would certainly like to see a more varied choice of race compounds in addition to the K1 and K2.
 
Metzeler Racetec RR

I'm using both front and rear K1 and K2 compounds depending on track temperature.
 
I couldn't get the k2 rear to work at all. Tried k2 on a cold day at cadwell and a warm at at Donny and both times killed them

I can tell you about the non slick version. The "Pro" version is a race tyre, while the "Racer" is a trackday tyre. As for feeling and traction "Pro" is by far superior.

A guy was on them yesterday, he was telling me he was in contact with a Michelin Technician through the website and was sending him pictures of the tyre through the day. The Michelin tech had him lower the rear to 22 psi hot by the end.

I've tried the 212racers slicks at Aragon Caldwell and oulton and at every track the rear chewed up within 3 to 4 sessions, I tried all sorts of different pressures but nothing stopped them. However The 212 go pro treaded tyre is brilliant, the wear rate is superb and they grip really well. But as said the Bridgestone vo2s haven't been added into the test and they are in my opinion the tyre to go for over the dunlops. They have excellent grip and wear and are a really good price. After using them i wouldn't buy a Dunlop over them.

To get better wear from the Racetec RR rears I had to change my riding style. I've found that I get better wear rates if I'm smoother and more progressive with the throttle. I'm normally quite abrupt with the throttle on corner exit but by being smoother I extended tyre life. The other benefit was that I could actually apply the throttle much earlier than normal after apexing and make better advantage of the superb grip that they offer. It ultimately led to faster lap times. What I have noticed about the rear Metzeler race tyres is if you are too aggressive with the throttle tyre life reduces significantly and more so than other brands.

Since becoming a lot smoother I've been able to use both the K1 and K2 rear compounds in hot and cold conditions respectively. I have always been able to use the K2 but since reviewing a lot of data over the winter, and making a very conscious effort to change my riding style, my K2 wear rates have drastically improved.

I'm sure that I would get better wear rates if I changed tyre brands but I'm really happy with the feel and grip of the Metzelers so I am reluctant to change.
 
Lap Times

Every track I've been to this year I've managed to lap within the 110% qualifying time limit for SSTK so it's been pretty successful and well worth the effort.
 
You're racing sstk1000?

What you doing round cadwell then?

I've only been on the bike 4 times this year so going to have to get me act together at the weekend so its not to embarrassing
 
Racing

I stopped racing a while ago! I've only visited Cadwell Park once this season and that was back in April. Lap times were a rather pedestrian 1:40s.
