In series production, the Aprilia Tuono 660 Factory is a well-made motorcycle.
However, the series suspension is not as sophisticated in some aspects as one might wish. Hard impacts and bumps in the road are passed on to the rider in a targeted manner.
Among other things, this is due to the overdamped suspension strut. This has been corrected in the Wilbers solution and the negative spring travel has also been adjusted.
The fork with its linear 9.5N/mm springs is clearly too stiff for road use and thus unnecessarily takes away ride comfort.
For road use, we provide progressive fork springs with 8.5N/mm to 10N/mm and a clearly adapted air chamber, which, however, also offers sufficient reserves for occasional use on the racetrack.
For focused race track use, we recommend our 642 S Competition shock, linear fork springs with 10N/mm and our high-quality “GP5 new racing formula” fork oil.
The basic edition of the Wilbers Adjustline mono shock absorber comes along with the same technology as the more complex versions. The difference is that here we leave out the compression reservoir and thus the options for adjusting high- and low-speed compression. Nonetheless this shock absorber does not make any compromises concerning response behavior or durability. The radial piston, wet run, teflon guided self-aligning bearings and other features redefine the quality of a standard shock. Like usual the spring preload can be continuously tuned and the rebound can be set over an open-bleed system in 22 clicks. The shock absorber can be retrofitted with many other Wilbers accessories.
