In MOTORRAD (issue 07/2023), sport and sport-touring motorbike tyres were tested on the KTM 390 DUKE in the dimensions 110/70 R17 and 150/60 R17.

Three manufacturers received the test rating "very good" BRIDGESTONE S22, METZELER M9 RR, MICHELIN ROAD 6

One manufacturer received a "good" DUNLOP GPR 300

Two have to be content with a "satisfactory".  CONTINENTAL CONTIMOTION CHENG SHIN CST CM-615 CM-616

How MOTORRAD tests

A quick tyre test on a country road? Not conceivable! Such tests are only seriously feasible on specially designed test tracks of the tyre industry. In this case, we were able to use the premises of the Japanese manufacturer Bridgestone in Nettuno (near Rome). For the asphalt test, we used the 2.2 km long "Carrera track" with many bends, for the wet test we used the permanently watered, 1.6 km long handling track. These criteria are the focus of the MOTORRAD evaluation:

  • Manoeuvrability ...is the steering force to bring the bike into a leaning position and keep it in line in alternating curves.
  • Limit behaviour* ... stands for the controllability of the tyre at the limit. Tests on wet and dry roads.
  • Steering precision* ... in passages of varying speed with complicated curve radii. Provides information on whether the motorbike follows the desired course, which is determined by the steering forces, or whether significant line corrections are required.
  • Cornering stability ...tests rocking in (alternating) curves and on bumps. Tested in different modes and when accelerating at an angle.
  • Straight-line stability ... is tested at high speed. Does the motorbike remain stable on course, or does oscillation interfere with the ride?
  • Acceleration grip* ...refers to lateral control and power transmission in fast corners (wet/dry).
  • Suspension* ... is the lateral control at maximum lean angle (wet/dry). A tightrope walk that is only possible on a closed track.
  • Set-up torque ... refers to the motorbike's set-up when braking in a leaned position. This reaction must be compensated for with a counterforce (pushing) at the inner end of the handlebars.
  • Filling pressures**: Road / wet (v/h): 2.0/2.2 bar.

*Sections marked with an asterisk are transferable to motorbikes that have a similar geometry to the KTM 390 Duke. **Indicated is the price range for a set of tyres (front/rear) in the tested version in common tyre online shops, as of 1 March 2023.

 

BRIDGESTONE S22 - "Conclusion: The Bridgestone S 22 is a sports tyre that shines in this test above all with its excellent everyday qualities. Perfect handling is joined by 1a rain qualities with the best braking values in the test."

METZELER M9 RR - Verdict: "Sportiness in sun and rain - the Metzeler is a recommendation for cornering junkies, whatever the weather. For a sports tyre, a very unusual and, in this test, very impressive combination."

MICHELIN ROAD 6 - Verdict: "The bottom line is that the Michelin offers a very balanced package for everyday riding. Beginners who ride their 125 or 48 hp bike year-round will quickly come to appreciate the Road 6's good-natured characteristics."

DUNLOP GPR 300 - Conclusion: "With the Dunlop, an entry-level bike like the 390 KTM in this test clearly gains in sportiness. Even in the rain, the GPR-300 delivers enough grip to push around corners with decent confidence."

CONTINENTAL CONTIMOTION - Conclusion: "In good weather, the ContiMotion is really fun on country roads, even if they are small and winding, and leaves a good impression. In the rain, its restrained grip quickly makes it lack confidence."

CHENG SHIN CST CM-615 CM-616 - "Conclusion: Fair-weather riders on 125s won't feel any shortcomings, but in the rain you quickly reach the CST's limit. On bikes in the 48 hp class, however, the tyre is not a recommendation on dry or wet asphalt."

Also in the next issue there will be a test and technical analysis tyre wear. Which factors are decisive for outstanding mileage?

Mitas is expanding its SPORT FORCE+ RS tire range with larger sizes.

Expected to hit the market in April 2023, the additional sizes, 120/70ZR17, 180/55ZR17 and 190/55ZR17, expand the range to a total of six sizes.



 

Although the tire had already been removed from the Michelin portfolio and was no longer available, lo and behold, the MICHELIN PLOT POWER will be relaunched again in 2023.

We cannot say whether so many customers mourned this, and the 2CT remains in the program.

"Sumitomo Rubber Industries, Ltd. is introducing DUNLOP SPORTMAX Q-LITE, a versatile diagonal tire with high grip that can be used on a variety of racing tracks and roads starting in the 2023 season. Seven sizes are available.

The Dunlop SPORTMAX Q-LITE has a new design pattern related directly to the high-grip tire of the "Q-series," a single R-tread pattern, a high-grip mixture, and an optimal combination of structures to achieve sufficient grip performance for sporty driving and the road. It is a diagonal tire with a long lifespan. You can confidently drive in various driving situations, from cornering, touring, daily tours, and circuit courses.

Main features and representative technologies

Profil pattern that achieves high drainage performance and wear resistance Long grooves that penetrate the contact area at all lateral inclination angles, changing the angle from the center of the tread to the shoulder to achieve high drainage performance The groove form and angle are improved by wear simulation and enhanced durability by suppressing uneven wear Handling profile for gentle handling By using a single R-profile with a uniform curvature radius of the tread cross section and suppressing ground shape changes during turning, the control performance during turning is significantly improved compared to conventional products

  • With linear handling, we have achieved steering performance that allows you to move freely at any lateral inclination angle Newly developed high-grip carbon mixture By using a high-grip full carbon mixture, it supports driving on circuit courses with high grip performance that shows itself over a wide range from the road to corners. In addition, the structure is tuned according to size to optimize stiffness.

Available in Japan in 2022, probably not available in Europe until 2023."
