It’s great to see firms launching new supersports rubber, so well done to Dunlop, which has just released the new Mark 4 version of its SportSmart sporty road tyres. It sits a few levels below the SportSmart TT and the road-legal race fitments like D212 GP Racer and D213 GP Pro, and is aimed at road use on sports bikes, with the odd bit of track action thrown in here and there.
The firm says the new rubber incorporates its latest rubber and carcass technology, including a new compound that gives ‘previously unattained levels of grip’.

There’s been a lot of focus on the front tyre, with handling improvements coming from a new casing construction and optimised ply tensions. The rear also has a tweaked carcass build, with a new sidewall and shoulder construction. Dunlop’s Multi-Tread technology uses a mix of high-silica compounds to give better grip on the sides for maximum lean angles, and harder wear in the middle for better mileage – important on a road-biased tyre like this.
The new SportSmart Mk4 tyres are in shops now, only in 17-inch sizes with a 120/70 front and 160, 180, 190 and 200 rears.
