From February 2010 onwards Bridgestone’s latest “full spec” sport touring tyre will be available in European markets. The Battlax BT-023 replaces the BT-021, and the Japanese manufacturer reports that the new tyre offers a significant upgrade in mileage and wet performance compared with its predecessor, as well as by meeting the handling expectations of the most demanding sport riders. All in all, adds Bridgestone, the BT-023 provides a wider range of choices for larger bikes by delivering consistent high-level touring and sport riding performance.

For the first time in their long history, Michelin® and Harley-Davidson® have joined forces to develop the all-new MICHELIN® Scorcher™ “31” tire, which carries both companies’ trademarks on its sidewalls and the signature Harley-Davidson logo carved into the shoulder.

A newly developed Bridgestone motorcycle tires for heavy and powerful Tours - motorcycles.
These new tires EXEDRA meet the high expectations of real Tour rider.
The modern rubber compounds provide the liability and a very high mileage.
To guarantee safety and driving pleasure.

Michelin has just released a new TV ad for the last MotoGP Grand Prix of the season in Valencia (Spain).

Through this commercial, Michelin wants to thank the teams and pilots who trusted the Group during the 36 years of Moto Grand Prix championships.
42 pilots, prior to this week-end last event, won one or more times riding on MICHELIN tires, giving the brand 360 victories in Premier Class category. The new TV spot will be broadcast 19 times on the sport channel Eurosport between October 24th and 27th, 2008.

Bridgestone’s new Battlax BT-028 radials will be the only original fitment on the new Yamaha VMAX when the power cruiser hits the street in 2009.

The machine will be riding on 120/70 R18 (59V) on the front and 200/50 R18 (76V) on the rear.

The front tyre features a multi-cross belt construction with a compound chosen for light handling and longer wear life for touring sport. Optimisation of the pattern, compound and construction gives the front tyre a light and neutral handling character, making it easier to control big and powerful bikes.

 

Innovation requires finding solutions in areas that make conflicting, seemingly irreconcilable demands on product performance. In a tyre, it’s all about maintaining balance. In theory, improving performance in one area means making sacrifices in another. Refusing to accept that premise, Michelin develops technologies that make it possible to simultaneously improve performance in different areas. That’s the price of progress, which is meaningful only if advances are made across the board. And that’s what Michelin has achieved with the Anakee 2, a new tyre for the market’s top-performing adventure touring bikes.
 

Bridgestone has launched Battlax BT-016, an advanced hypersport tyre seen for the first time at the EICMA 2007 in Milano. It is designed to give maximum sporty performance to riders who are passionate about sport bikes – with the chance to enjoy the exciting grip performance of Bridgestone’s MotoGP multi-layer compound technology.
 
Compared to the BT-014 it will progressively replace, the new BT-016 provides total handling improvement in all riding modes – with noticeably better contact feel, feedback, stability and grip – as well as longer wear life and lower noise levels.
 

Hiroshi Yamada, manager of Bridgestone‘s Motorcycle Sport department, is sure to be a very busy man in 2007. Supplying the rubber for Ducati Marlboro, Gresini Honda, Kawasaki Racing, Pramac dAntin and Rizla Suzuki means that he has five teams and four different manufacturers to work with during a season in which Bridgestone have to make their own, specific adaptations to historic shift from 990cc bikes to the new, smaller SOOcc prototypes. With this comes the added responsibility of adapting to particular individual demands, although Yamada is confident of finding a solution for everyone.
“Generally, our plan has been focused on getting the direction of tyre construction correct, but now we will be starting to adapt the tyre to meet the requirements of each of our teams. Some riders still require additional support to have tyres that work with their riding style. We can only offer reassurances at this early stage that we will do everything to fulfil our teams‘ and riders‘ requests,“ he commented after last week‘s Official Test in Qatar.

The Michelin Pilot GT is the all-new tire for the Honda GL1500 Gold Wing, featuring the latest advances in rubber composition, carcass construction and profile. It delivers exceptional handling, maneuverability and mileage, without compromising wet or dry grip. Though the GL1500 is out of production, its tire sizes consistently rank among the top ten in unit sales. Capture a piece of this important market with the new Michelin Pilot GT.

  • Four crossed plies in the front tire carcass provide excellent stability both in a straight line and while cornering
  • Optimized tread thickness helps minimize shimmy both when the tire is new and at the end of its tread life
  • Triangulated front profi le facilitates low-speed maneuverability
  • Three crossed plies and two crown plies help make the rear carcass highly resistant to side loads
  • Distinct rubber mixes for front and rear tires are optimized for durability, grip, and traction
  • Bias Ply construction

Motorcycle Tires Under Extreme Load: A Look at the Physics of Grip

This text dives into the extreme stresses placed on motorcycle tires at high speeds, highlighting the impressive performance of these seemingly simple components.

Forces at Play:

  • < 200 HP: The engine's immense power needs to be transferred to the road through the tire, posing a huge challenge for grip.
  • < 270 km/h (168 mph): At this speed, the tire rotates 1.5 times per second and travels 4.5 km (2.8 miles) further than the front tire due to "spin" caused by slippage.
  • Torque: The engine's gearing amplifies torque at the rear wheel, resulting in strong pulling force.
  • 1450 Newtons: This immense force pushes the motorcycle and rider through the wind, with the tire providing the frictional force necessary for forward movement.
  • 150 kg (330 lbs) Wheel Load: The motorcycle's weight rests on the tire, further increasing friction and wear.
  • 4.5% Slip: At high speeds, some slippage is unavoidable, leading to heat generation and wear.
  • 100 Degrees Celsius Rubber Temperature: Frictional heat can significantly raise the rubber temperature, affecting its properties and grip.
  • 270 Newtons Centrifugal Force: The centrifugal force on each individual belt thread within the tire is enormous and can lead to structural damage.
