ME 888 MARATHON ULTRA 【100/90 - 19 M/C 57H TL OW】 輪胎

The ME 880 MARATHON (ME 880), which boasts of being the most trusted "V-Twin" custom motorcycle rider for Harley and DAVIDSON, as well as the ME 880 MARATHON (ME 880), a product with improved mileage among its superior performance by builders. MARATHON ULTRA (ME 888)..
Many aspects of the ME 888 have been redesigned, including the compound, profile, tread pattern and tread shape, to increase mileage without sacrificing the superior grip, nimble handling and wet performance that the ME 880 was known for..

Compound
For the compound, we have adopted a new compound with superior wear resistance and uniformity of wear..

Improvement of wear resistance
By blending superior wear-resistant polymer and new resin, excellent mileage is achieved while maintaining grip on wet roads..

Wear uniformity
Metzler's proprietary Compound mixing technology allows the ingredients of the compound to be mixed more finely and evenly to produce a compound. This ensures very uniform wear and minimizes the loss of performance after the Tire is reduced to the smallest possible extent..

Profile
Like the ME 880, the ME 888 uses a completely different profile, but with a BiasSize of Polyester carcass (and a BeltedBias of AramidBelt)..
The shape from the TireCenter to the Shoulder is flatter than in the ME 880 (Figure 1) to prevent deformation of the tread surface.. This reduces the stress on the entire Tire and allows for better mileage.

Tread patternDesign
In ME 888, a part called "CompoundBridge" (Figure 2) is placed between Groove and Groove.. This restrains the deformation of the tread surface and performance degradation during wear and improves the mileage..
Moreover, the angle of the Groove is changed according to the direction of the force applied to the tire from the road surface (Figure 3)..
The force applied to the Tire from the road surface depends on the bank angle and the direction of rotation of the Tire..
By carving the Groove at an angle that matches each bank angle and the direction of rotation of the tread, the stress on the tread surface is reduced, which prevents uneven wear and further improves the mileage..

Ground plane shape
The ME 888 has a ground plane shape that is 5% shorter and 15% wider than the ME 880..
By shortening the ground shape, the time it takes for the force to be applied to the tread surface is shortened and the stress applied to the compound is reduced.. This further improves the mileage.
Also, by widening the ground contact area, the ground contact area becomes larger and has a higher grip.. The strong torque of the V-TwinEngine is fully transferred to the road surface..

Summary
The ME 888 MARATHON ULTRA has been designed with new features such as Compound, Profile, Tread pattern design, and Ground plane shape to provide the superior grip, nimble handling, and It is the Tire that improves the mileage without sacrificing the wet performance..
It also provides excellent wear uniformity and reduces the degradation of tire performance, ensuring that the ME 888 MARATHON ULTRA will continue to deliver superior performance for many years to come..
