Recommended For

— and it's specifically a strong choice. Slipper clutch systems (found on KTM, Bajaj Dominar, TVS Apache RR310, and others) create higher interface stresses on the clutch plates during engine braking. The 40-grade viscosity in the RS series maintains a stronger oil film at the clutch interface, which extends clutch plate life and improves slipper action consistency. JASO MA2 certification confirms it meets the friction requirements.

About This Product

The Carbo Oil 4T Motorradöl 01 RS 10W40 is engineered for performance 150cc–250cc motorcycles with slipper clutch systems and high-revving engines. API SP certified and JASO MA2 rated, the 10W40 viscosity maintains a strong oil film at the clutch interface — enabling clean gear changes under aggressive downshifts without clutch judder. Designed for KTM Duke 200 and RC 200, TVS Apache RTR 200 4V, Bajaj Pulsar NS200 and RS200, Yamaha MT-15 V2, and Honda CB300R. Stable viscosity across wide temperature swings: cold city-morning starts to highway operation above 40°C ambient. LSPI protection included. Change interval: 5,000–7,000 km.

Frequently Asked Questions

When should I choose 01 RS 10W40 over 01 RS 10W30?

Choose 10W40 when your bike has a larger displacement engine (200cc+), a high-output liquid-cooled engine, or when you regularly ride in temperatures above 35°C. The 40-grade operating viscosity provides a thicker protective film for high-displacement engines running hotter. Confirmed OEM-compatible bikes for 10W40 include: **KTM Duke 200** (OEM spec: 10W40 or 15W50), **KTM RC 200** (same), **TVS Apache RTR 200 4V** (OEM: 10W40), **Bajaj Pulsar NS200/RS200** (OEM: 10W30 or 10W40 per Bajaj chart), and **Yamaha MT-15** (10W30 or 10W40). Note: For the **Bajaj Dominar 400**, the OEM spec is 10W50 — use the 01 RS 15W50 instead. For the **KTM Duke 390**, OEM spec is 15W50 fully synthetic — also use the 01 RS 15W50.

Is the 01 RS 10W40 suitable for motorcycles with a slipper clutch?

Yes — and it's specifically a strong choice. Slipper clutch systems (found on KTM, Bajaj Dominar, TVS Apache RR310, and others) create higher interface stresses on the clutch plates during engine braking. The 40-grade viscosity in the RS series maintains a stronger oil film at the clutch interface, which extends clutch plate life and improves slipper action consistency. JASO MA2 certification confirms it meets the friction requirements.

Will using 01 RS 10W40 improve the shift quality on my performance motorcycle?

Many riders report noticeably smoother and more precise gear shifts after switching to a quality semi or fully synthetic API SP oil. This is because the synthetic base stocks in the RS series maintain stable viscosity across the full temperature range — from cold start to full operating temperature — which means the clutch and gearbox operate in consistently lubricated conditions throughout the ride. The improvement is most noticeable on bikes with close-ratio gearboxes.

Can I mix the 01 RS 10W40 with my existing motorcycle oil during a top-up?

While mixing oils from different brands or grades is not ideal, a small top-up of the same grade (10W40) from the RS series will not cause engine damage. However, we recommend avoiding mixing synthetic and mineral oils in large proportions, as the additive packages can sometimes interfere. For the best performance of the RS formulation, do a full drain and fill at the next oil change interval.
