Metzeler Racetec will continue as the official tyre supplier and presenting sponsor of both the National Superstock and National Superstock Cup championships in a two year contract announced today by Dorna UK, the commercial rights holder of the Bennetts British Superbike Championship.

Metzeler Racetec has been the official control tyre of these two heavily subscribed production racing championships since 2005 and the partnership will continue through both the 2007 and 2008 seasons.

The Metzeler Racetec National Superstock Championship and Metzeler Racetec National Superstock Cup will each be decided over 13 rounds held alongside the country’s premier motorcycle racing series, the British Superbike Championship.
The agreement with Metzeler Racetec confirms that they continue as the Official Tyre Supplier to the championships, providing all competitors with a tyre package throughout, and at a significantly subsidised rate. Additionally Metzeler Racetec will also reward performance on track with the provision of free of charge tyres for podium-placed riders against their season package.

Tony Partis, managing director of Dorna UK, commented: “We are very pleased that the competitive nature of the Superstock series has attracted so much support from Metzeler Racetec. With the packages that they have put in place we are maintaining the key values of the Superstock series, of terrifically close racing at a very affordable price.”

Managing Director Business Unit Moto Pirelli Ltd, Gianmarco Spigolon, added: “We have watched as the British Superbike Championship has gone from strength to strength and wanted not just to be part of it, but to add to the spectacle. The Superstock series always sees full grids and full-on racing so Metzeler Racetec are very exited about our association and look forward to seeing it develop even more throughout the next two seasons.”

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

Metro Tyres – India‘s one of the leading tyres manufacturers is planning to roll out Tubeless motorcycle tyres in technical collaboration with continental AG of Germany. These tyres will be manufactured primarily for overseas markets to cater to the demand of tubeless tyres among the global two wheeler players like Honda, BMW and Yamaha etc.

 
Later on Metro will also roll out these tubeless motorcycle tyres in the domestic market.
 
Mr. Jorg Essiger, Managing Director, Continental AG, Germany who is especially here to finalize the details said, “We are witnessing an equal demand for Tubeless motorcycle Tyres in Asian market too as in Europe. And to cater to this growing market we are rolling out Tube less motorcycle tyres in partnership with Metro Tyres, for which all the required technical know how Continental is providing.
 
“On the occasion Mr. Max, R & D Head Continental AG, Japan said, “ India is going to be a major export hub for the two wheeler industry particularly for motorcycle and we at continental will further fueling the growth by flitting up Tubeless Tyres that are of international Standard, ECE approved, Technological superior with much longer life”

AVON PRESENTA UN NOUVA SPORT TOURING TYRE

Avon is to launch a new sport-touring tyre range named Storm-ST, replacing its highly popular Azaro-ST product. Storm-ST has already been tested and approved for fitment to all major motorcycles in conjunction with the well-respected German TUV agency.

Available from Autumn 2006, Storm-ST is available in 15 sizes:

Fronts AV55 - 110/70ZR17, 110/80ZR18, 120/60ZR17, 120/70ZR17, 120/70ZR18, 130/70ZR17

Rears - AV56 150/70ZR17, 150/70ZR18, 160/60ZR17, 160/70ZR17, 160/60ZR18, 170/60ZR17, 180/55ZR17, 190/50ZR17, 200/50ZR17.
Storm-ST is the first tyre to include Avon’s new ‘Reactive Footprint’ [RF] technology.
Reactive Footprint technology marries Avon’s unique variable belt density [VBD] carcass with Lifetime Profile Engineering [LPE] to produce a footprint which changes size and shape, depending on the bike’s lean angle, for the full life of the tyre.

The result is a contact patch that grows as the bike leans, giving more grip in corners whilst minimising wear rates when travelling in a straight line.

This technological breakthrough could eliminate the need to use dual compounds and would help solve the uneven wear problems associated with them.
Pete McNally, Avon’s Motorcycle Product Manager explained, “These new technologies combine to make a tyre that doesn’t just handle well when new but also in the last 25% of its life.” He continued, “With Storm-ST it’s not just the compound that’s harder in the centre and softer at the edges, it’s the whole tyre. We believe we are the first manufacturer to produce a reactive footprint tyre for motorcycles.”

In addition to Reactive Footprint technology and Lifetime Profile Engineering, Storm-ST is bristling with an impressive array of advanced features:
A new Super-Rich Silica compound [SRS] delivers sure-footed grip in both wet and dry conditions and allows the tyre to quickly warm up to reach optimum working temperatures.

‘Inverted Front Grooves’ (IFG) on the front tyre, a system pioneered by Avon in the late eighties and only now being adopted by the competition, resists ‘stepped-wear’ and ‘cupping’ to deliver smooth handling throughout the tyre’s life. A further advantage of the IFG configuration is improved wet braking and shorter stopping distances.

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.
