Wilbers.
Yamaha's factory springs are too soft, so the forks sink under the weight of the motorcycle. When braking, the problem is even more obvious. When you release the brake there is a rapid rebound, so it is difficult to keep the direction, and the motorcycle is constantly dangerously forced out of a bend. To some extent, the forks can be adjusted, which does not make sense with worn-out material. With the installation of Wilbers progressive springs, this problem is solved. The feel, position on the road, controlled dive, the improved grip and the comfort while driving is amazing. Closing the handlebars, skidding on a poor road and stalking has been eliminated.
Yamaha's standard shock absorber is too soft for the average driver. On a bad road, motorcycle bounces in corners, squats when accelerating, and under the weight of luggage and passenger simply can no longer absorb the bumps. With the settings, it's very limited and I didn't gain anything from it, just lost on comfort.
The Wilbers 641 shock absorber (hydraulically adjustable spring preload is a must have because you can't reach the nut with a wrench) has improved riding in all aspects. The motorcycle is basically taller as it doesn't sinkt under its own weight. Perfectly dampens bumps on the road, it is just right hard and soft. Therefore, the ride is comfortable and effortless. The feel, position, feedback and control in any situation is worth the money invested.
I highly recommend upgrading the suspension. I paid 650 € for the shock absorber, and 180 € for springs.
