The Aerox 155 issue with the front fork has been solved with the upgrade. The srpings have superior quality. You need 20W fork oil, around 62ml for each leg. 2 fork oil seals are also required for the upgrade.
Overall my experience with the upgrade is satisfactory. The price point is expensivedue to it being imported. Highly recommended.
Awesome suspension. Changed front fork pipes to himalayan"s and rear to this. I think my mt15 is not another than Himalayan through the rough roads! And easy adjustability means you can stiffen it up and go on rides to utilise the Yamaha DNA.
