Motorex - Top Speed Synthetic 15W-50 4-Stroke Engine Oil

Motorex Top Speed Synthetic 15W-50 is built for riders who expect smooth, consistent performance across every ride. Using Motorex’s MC (Molecular Converted) technology, it refines premium base oils to deliver full-synthetic-level protection, excellent film strength, and reliable clutch feel in demanding conditions. It’s engineered for medium to large displacement 4-strokes — but it’s also the recommended transmission oil for KTM, Husqvarna, and GASGAS 2-stroke models, trusted by the manufacturers themselves.

Why we like it: it’s a true do-it-all oil. It runs clean, keeps engines and gearboxes quiet, and holds up under heat without fading or thinning out. Whether you’re hammering laps or logging long miles, it delivers steady oil pressure, smooth shifting, and noticeably less clutch chatter or drag.

Why it’ll work for you: it’s designed to handle the heat and friction of modern motorcycles — from 4-stroke engines to 2-stroke transmissions. With JASO MA2 certification and API SM/SN/SP ratings, it ensures smooth clutch performance and excellent wear protection. Stable, durable, and manufacturer-backed, Motorex Top Speed 15W-50 is the one oil you can confidently run in both your 4-stroke and 2-stroke machines.

Key Features:

  • Fully synthetic, high-performance 4-stroke oil
  • High friction coefficient
  • Decreases oil consumption; protects against wear
  • No moly additives
  • Optimized clutch performance according to JASO MA

Asurion "Assures" nothing!
Asurion has terrible Customer Support. All machine based. They give you no phone # for human interaction. Their online Support process is very close-ended. It is a checklist designed to frustrate purchasers whose issue lies outside only the very issue. My issue: I bought "Cuisinart TOB-40FR Custom Classic Toaster Oven Broiler, Silver (Renewed)" on May 26, 2024. It stated it had a 90 day warranty. So I bought an Asurion Protection Plan also to cover it for 3 years. The toaster started flaking off metal finish inside the oven over the cooking area. I tried to file a claim with Asurion and they told me the Manufacturers warranty was still in effect and I should contact Cuisinart. This despite the oven was sold with a Amazon Renewed verbiage stating a 90 day warranty. And they have nothing on their "Machine Checklist" to cover this eventuality. And I would assume I am not the only one who takes the "Renewed" route and backs it up with a "Protection Plan". They will frustrate you no end. I suspect, like many insurances, they seek to deny, deny, deny, in hopes the purchaser will give up.

GIFT CARD AS REPLACEMENT, NO CHOICE OF CHECK OR REPLACEMENT. GOOD COMPANY
PROS: * A decent company, responsive and fair. * Allows you to buy items from anywhere you want, and buy the warranty at Amazon. * Provides better coverage than other warranties, and covers more, including breakage! CON: They don't send you a check in order to buy wherever you want, send a replacement, or give you a choice. Instead, they send you an Amazon Gift Card. That's OK if you're a big Amazon shopper, but sometimes, you can get a better price elsewhere.
