Metzeler Racetec RR £273
The Racetec RR is the latest evolution of the Racetec Interact and comes directly from Metzeler’s experience in road racing. This environment challenges a tyre as it has to work in high and low temperatures, at high average speeds on a wide variety of surfaces, and even take the odd jump into account. The new RR is designed to suit all of these situations.
According to Metzeler, the main benefits of this latest version are improved grip, precise and stable handling and consistent performance. Unlike the old Racetec Interact, all the sizes and compounds are road legal. The Racetec RR is available in three compounds, K1, K2 and K3. K1 is the softest compound with a blue stripe in the tread, K2 medium has a green stripe, and K3 is the hard compound with a yellow stripe and lettering. They were tested at Jerez by MCN’S Chief Road Tester Michael Neeves.
What are they like?
Racetec RRS give a consistent and stable feel, speedy warm up and great feedback. Within a few corners of our test at the Jerez circuit in Spain, the road-legal rubber was almost up to temperature, giving the confidence to push towards the end of my very first lap.
Once up to temperature the new Racetec rubber delivers a huge amount of grip, which gives confidence to reach elbow-down lean angles of lean.
We have tested both the racy K2 compound and the more road-oriented K3 version, on a selection of the latest 1000cc sportsbikes. There’s a noticeable difference between the two compounds — the K2 is a race tyre offering huge amounts of grip but won’t have the staying power of the K3.
In fact, we were very impressed with the longevity of the K3. After a full day of testing we attempted a 40-minute continuous track stint on the K3, the equivalent of two laps of the TT course. The K3 was consistent throughout, which was really impressive. It was so consistent we could make the rear slide by a fraction on the exit of a fast third-gear corner by increasing exit speed a little each lap until eventually finding the limit. On each lap the grip was almost identical, which meant progressively pushing back my braking and exit points and relying on having the same amount of grip on each lap.
Stability was excellent at Jerez, but a tyre that’s stable at the Isle of Man TT and North West 200 is always going to make easy work of a smooth track such as Jerez, where the speeds are also far slower. And despite offering excellent stability, the Racetecs didn’t hinder the bike’s ability to turn in, which is a big compliment.
