【Supreme Technology】Over suspension (for on-road bikes) Review

I feel it converges quickly … even on rough surfaces.

I happened to read an article about OverSuspension here in a magazine, a technology that was banned in F1? Wow! However, because our motorcycle is the MT-09SP, which was model changed in 2021, the conformity of each parts is ambiguous, and some manufacturers distinguish between ~21 and ~20 and ~21. Some manufacturers distinguish between "~20" and "21", and this product was also labeled as "~21" for MT-09.
However, the store where I bought the motorcycle happened to have an XSR900, and when I compared the rear axle area, the size was obviously different, so I decided that the MT-09 size indicated by the manufacturer's label would not fit the New Model. I measured the size of Axle Block of MT-10, etc., and checked YZF-R1, and could not find the same one, but I found out that the part number around Rear axle is the same with YZF-R6 of the current model 17~, so I ordered it and confirmed the installation without trouble. I ordered it and was able to confirm that it was successfully installed.
Please note that this product is compatible with the YZF-R6 for 17- when installed on the MT-09 from the 2021 model year.

Installation is not particularly difficult; simply replace the Axle Block with the OEM one.
However, it is tempting to tighten the mass damper so tightly that it is likely to fall off when installed, but you should be careful to Overtorque it so that it does not need to be tightened that tightly in compliance with the stipulated Torque in the instruction manual that comes with the mass damper.

Impression after installation was that it was quite heavy because of the Tungsten weight, and I wondered if it would become heavier under Spring, but it converged very quickly when passing through wadachibore, gap, etc.
Sorry for the onomatopoeia of the analogy, but what used to be like a bang will now be like a thud.

There is an explanation that traction is … in Circuit, etc., but even in Street, it has the advantage of fast convergence in rough road conditions, and I felt that it is highly effective enough in Street, such as touring. View detail
