The YSS MZ366 rear suspension is fun to feel the change even if you move the extension side one step.
Even on the pre-road, you only need to move it a quarter turn to feel the change.
Setting the rear suspension will also affect the front suspension.
If the front suspension does not have setting function, setting the rear suspension of YSS to match the front suspension will improve the ride quality.
Of course, it can be set to improve the turning performance.

The yss MZ366 will impress you when you install it and ride it, the stability of the cornering and the small unevenness of the road will not be transmitted to your butt and it will keep a constant state. The adjustment of the extension side can be felt from 1 click and setting is fun. It will impress every rider!

In case you missed it …
And it helps that the Overhaul cost for the Rear suspension is so cheap!

Cospa is the best.

It is cheap but the performance does not compare with the OEM.
Better than I thought.
However, the stretch of 60 steps is too much.
Pre-road is not Double nut and Screw fixing is impossible.

It installed in RZ-250R

I bought it on Webike.
The width and diameter of Color on the suspension side joining LINK and suspension were slightly different, so it was not possible to put it on. Although it may be an individual difference, I corrected it by taking about one hour Small to scrape.
As a performance, I think that it is sufficiently above the price,
I am satisfied..
It's quite good..

I exchanged it from OEM of RZ 250 R.
After full restore, it was exchange from Shock which was completely missed, so I do not know the difference, but it is cheap anyway!
OEM Product and Large There is no difference in Gold amount, but Spring pre-road adjustment (Stepless) , Rebound adjustment (60 steps) , Vehicle height adjustment (+10 mm Meter) There is a function, it is enough if you need it for general use range.
After exchanging, I ran about 3,000 km, but I have never felt anything uneasy at the moment.
Spring also Red (Depending on MODEL it seems Black color) So it looks good too.
Instruction Manuals are also substantial, and installation was done without difficulty.
However, it was hard to enter unless the upper and lower axes were precisely aligned in parallel at the time of installation, but accuracy is good and the clearance is small, so there is no problem.
Anyway, Large satisfied with outstanding COSPA ♪
