From the very first sketch, our tower was designed with an additional support to relieve the load on the four original mounting points, which are often stressed beyond their breaking point under heavy use of the motorbike.
And so our ‘Spider’ was born: simple and effective, it adds two mounting points to the frame – without modifying it – to take some of the strain off the four original points.
Given the numerous reports of cracks and tears in these, for the first generation (Euro5: 2021–2024) we consider it ‘essential’ to use it in combination with our tower in order to safely cope with the additional load of large navigation instruments, significant loads on our Front Rack, or even simply the mechanical stress resulting from more aggressive riding on rough terrain.
From 2025, and primarily on the Rally, Aprilia has modified the construction of the four original mounting points in a seemingly effective manner: the lack of reports of breakages or damage in that area on the new generation of Tuaregs allows us to fit our tower even without the Spider, although the latter remains strongly recommended for a more ‘sporty’ use of the bike;
We have therefore completely redesigned it to remain effective and reversible even with the new frames.
Mechanical stresses are now transferred to a wide aluminium collar that wraps around the frame over the largest possible surface area, thereby maximising stress dispersion and preventing localised strein in that particularly sensitive area.
