**α-13SP (REAR) adopts to HES-JLB structure. Please do not mount the tire of HES-JLB structure on the wheel other than the allowable rim width. (There are cases that the corresponding rim width might differ depending on the pattern even it has the same tire size.)
*SPORTMAX α-13 SP is a tire that enhanced the grip performance on dry roads for the purpose of shortening the time in circuit riding.
*In case of not performing the appropriate setting and the turning to the vehicle body and the suspension during circuit riding, there is a possibility the it does not exhibit the original performance and the stability might be impaired and it might lead to serious accident due to the accurence of abrasion, chattering and etc.
*In the lower temperature lower than 0-degress, there is a risk of cracking in the thread part rather that the imparting impact or knitting because the rubber falls. Please avoid riding on a low temperature such as less than 0-degress and moving the equipment vehicle and assembling to the rim.
*Please do not use the tire which a cracked in the thread part.
*Please be careful to it because there are cases wherein it does not obtain enough grip performance in case the tire is cold immediately after start riding or in case of rain..

[CONCEPT]
It improves ground contact and grip absorbability more than α-13 which is popular in production races such as ST250 and CBR CUP.
It achieves sufficient grip/life in high dimension and it corresponds to wide temperature range.
ARRC AP250, designated as a one-make tire of MFJ JP250 class.
[Product Features]
1. Adoption of newly developed compounds.
Based on the compound of the race replica radial tire "Sportmax α-13",
By blending the high molecular weight polymer and race fine carbon,
The coupling point of the polymer and the carbon increases, and the grip performance superior in a wide temperature range is demonstrated.
Also, it is excellent in wear resistance by the long chain of high molecular weight polymer is enhanced bonding force with carbon,
It achieves enough durability even in the race with the tire number limit.
2.2-Cut breaker structure (front tire)
Fast turning response with a high rigidity and lightweight 2-cut breaker structure light handling
It was achieved at a high level.
In addition, by optimizing the casing rigidity, it has greatly improved the sense of grounding of the road surface.
3. C.T.T (Chamber last tuning technology)
By optimizing the balance of the front tire and the rear tire chamber last at each bank angle,
The bank angle and the steering wheel angle are linearly synchronized to achieve smooth transient characteristics,
It achieves a light handling while demonstrating excellent turning properties. It provide feedback on the technology cultivated in Moto2/Moto3 and JSB1000 to support circuit driving and production races in the Ritter class super sports vehicles.
In addition, it is decided as a one-make tire to the 250cc class in the National and Asian Championships.
Racing Sports radial for production race for riders aiming for victory.
It is optimized for one make-up race.
