KTM specs the 10w60 for that engine so in theory they have designed the oil flow for the slightly thicker oil at high temperatures (i.e. the '60' vs the '50' in the designation). Without getting into the technical details, the 10w60 oil has about 30% more viscosity at VERY high temperatures, say 100 degrees C, than the 10w50. If you ride for prolonged periods at high speed, in high temp environments, or at prolonged low speed where the bike is prone to boiling over then it is very likely that paying the extra $5 for the 10w60 as the KTM engineers intended is worth it. If it was my expensive bike I would spend the extra $5 anyway.

Refer to owners manual **Q: Is this a 4 liter bottle?** A: I don't think that one is. Most 4 liter have a red picture and a screw top and most sellers indicate 4 liter ## Frequently Bought Together - Motorex Cross Power 4T Oil - 10W50-4L. 171-401-400 - 3 PK OEM KTM OIL FILTER 250 350 400 450 500 530 SX XCF SXF EXC EXCF 77338005100 - Twin Air Pre-Oiled Foam Air Filter (KTM 2016-2022) (125-530) - 79006015000A --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/11247618-cross-power-4t-oil-10w50-4l-171-401-400](https://www.desertcart.jp/products/11247618-cross-power-4t-oil-10w50-4l-171-401-400) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-14*
