Brno MotoGP 2014 Technical Preview from Tire Perspective
Brno MotoGP 2014
Following last Sunday’s Red Bull Indianapolis GP, the MotoGP pilots only had a few-day’s rest before returning to Europe for this weekend’s Czech Republic Grand Prix at Brno.
The Brno circuit, which hosts round 11 of 18 in 2014 MotoGP, provides challenges for the riders due to technical corners and many elevation changes.
At 3.35 miles, the 14-corner circuit has elevation changes of 230 feet, which is grueling on downhill braking. This type of circuit requires high levels of stability from the front tire, and exceptional grip from the rear to ensure maximum drive on the straight sections.
Because their are eight right-hand corners, and six left handers, the force imposed on both sides of the tires is nearly even. Due to this, asymmetrical rear slicks – though offered – will likely remain in the garage.
Also, Brno features an abrasive tarmac, which demands superior durability from the spec-Bridgestone tires.
Factory Honda and Yamaha riders at Brno will ride on rear slicks of medium and hard compounds, while the Ducati and Open-class riders will use the soft and medium compound options.
The main front slick options for the Czech Republic Grand Prix are the soft and medium compounds, while a maximum of three front slicks in the alternative, hard compound are also available to riders. The main wet tire for Brno is the soft compound, although every rider will be able to also select up to two front and rear wet tires in the alternative, hard compound option, Bridgestone reports.
Hiroshi Yamada, Manager, Bridgestone Motorsport Department, says “The Czech Grand Prix is always well-supported by fans and the spectacular Brno circuit with its big elevation changes has hosted two incredible races in the last couple of years.
“Marc Marquez’s amazing record continued last week at Indianapolis but we saw that many riders were competitive in America, and as every race passes there is great anticipation about whether Marc will once again be able to fend off his challengers come Sunday. The Brno round is also important due to the post-race test, the data from which will help form the basis of our MotoGP tire development for the 2015 season.”
Shinji Aoki, Manager, Bridgestone Motorcycle Tire Development Department, says “The Brno circuit features quite abrasive tarmac and elevation changes which place considerable stress on the tires, particularly the front.
“There are fast corners, as well as some mid-speed left right combinations so having a balanced bike setup at this circuit that uses the tires effectively is important here to ensure good lap times and durability, given the abrasiveness of the tarmac.
“The changes in elevation at Brno requires us to provide front tires with high levels of braking stability, while also giving good warm-up performance in the cooler morning sessions. The weather forecast for this weekend is for cooler temperatures, hence we have decided that the soft and medium compound front slicks are our main front tires for this weekend, although the hard compound front slick will also be available to riders.”
