KTM Motorex Oil Change Kit 15W/50 (1.7L) - Ready to Race

In this review of the KTM Motorex Oil Change Kit 15W/50 (1.7L), the bottom line is simple: this kit is aimed at riders who want a genuine, ready-to-use OEM oil change solution that keeps small-displacement KTM models ready to ride. The reviewer found the kit valuable because it combines a correctly matched semi-synthetic engine oil with an Original SpareParts oil filter, so routine maintenance becomes faster and less error-prone for owners of 390-series bikes. For anyone who prefers OEM components and a tidy, single-purchase service kit, this is worth considering.

Key Features

• Complete Kit: The package includes the oil and a genuine OEM oil filter so the rider has everything needed for a standard oil change without hunting for separate parts.
• Matched Oil Grade: Motorex Formula 4T 15W/50 semi-synthetic oil is chosen to meet KTM engine needs and provides reliable protection under varied riding conditions.
• Ready to Race Philosophy: The kit follows KTM's Ready to Race approach by supplying factory-approved fluids and parts to maintain performance and engine longevity.
• Exact Quantity: The 1.7 liter supply is intended to provide the necessary volume for a single oil change on compatible 390-family models, reducing waste and measurement guesswork.
• Genuine Replacement Part: Using an Original SpareParts oil filter helps ensure correct fit and filtration compared with generic filters.

Who It's For

This kit is best for owners of KTM 390 Adventure, RC 390 and 390 Duke who want a bundled, factory-aligned oil change option that eliminates the guesswork around oil grade and filter fitment. It is also useful for technicians and home mechanics who prefer OEM consumables for routine service to keep warranty or service records consistent.

Riders of larger-displacement motorcycles or those who need a larger oil quantity should look elsewhere, as this kit is sized specifically for small-displacement KTM and closely related sister models from Husqvarna or GASGAS. Those seeking specialty racing or fully synthetic oils with alternative viscosities should choose a different product.
