Adventure Bike Tuning!
Your KTM 890 Adventure R is built for exploring — our tune makes it even better.
The 2021 890 already improves on the 790 with more power, more torque, and smoother rotating mass. But with our performance calibration, the bike becomes noticeably more responsive and confident in real‑world riding.
What this latest 890 gained:
• +6 HP for stronger top‑end on open roads
• +10 Nm for easier climbs, sand, gravel, and loaded touring
• Wider dynamic range so the bike pulls earlier and holds power longer
• Faster, cleaner throttle response
• Optimised AFR and injection timing for smooth, predictable delivery
The difference off‑road is immediate — more control, more torque where you need it, and a bike that feels ready for anything.
Wellington KTM riders — if you want your KTM to perform at its best, get in touch.
