4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Unveiled for 2022+, the Tuareg 660 re-engineered the 659cc twin with a shallower high-clearance sump (240 mm ground clearance), torque-focused cams (80 hp / 70 N·m), a tubular steel trellis frame, and 240 mm fully adjustable KYB suspension.
Oil & Clutch Mechanical Engineering Note
Despite its shallower rally sump pan, the Tuareg 660 takes the same 2.30 L of full-synthetic SAE 10W-50 JASO MA2 oil and M20×1.0 fine-thread 1A023538 / HF138 spin-on filter—pre-fill the new canister 1/3 full before spinning it on.
Garage Wrenching Gotchas
- Huge advantage over tube-wheeled rivals like the Ténéré 700: the Tuareg 660 comes standard with outer-flange cross-spoke TUBELESS 21/18-inch wheels wrapped in Pirelli Scorpion Rally STR tires!
- For deep water crossings and fast trail servicing, the airbox sits high behind the steering head cover—accessible in minutes without pulling the fuel tank! Check oil warm and upright with the dipstick resting unthreaded.
5. Frequently Asked Questions (FAQ)
Are the 21-inch front and 18-inch rear spoked wheels on the Tuareg 660 tubeless?
Yes—both 90/90-21 front and 150/70 R18 rear wheels use perimeter-laced cross-spoke tubeless rims straight from the Noale factory.
How does the 204 kg wet weight and 860 mm seat feel on the Tuareg 660?
Because the 18.0 L tank carries fuel low down into the frame cradle and the waist is remarkably narrow, its 204 kg wet weight feels dramatically lighter and easier to pick up than top-heavy rivals.
What cold tire pressures does Aprilia specify for the Tuareg 660?
Solo tarmac spec is 200 kPa (29 PSI) front and 250 kPa (36 PSI) rear cold, rising to 220 / 270 kPa (32 / 39 PSI) loaded, or 200 / 200 kPa (29 / 29 PSI) baseline for off-road stages.
