Motorex - Power Synt Synthetic 5W-40 4-Stroke Engine Oil

Motorex Power Synt Synthetic 5W-40 4-Stroke Engine Oil is designed for riders who expect peak performance every time they twist the throttle. This fully synthetic, race-grade oil was developed for hypersport and high-output engines that demand maximum protection under extreme heat, RPM, and load. It delivers smooth power transfer, reliable clutch feel, and consistent lubrication across the entire rev range — exactly what modern performance bikes need.

Why we like it: it’s one of those oils that gives instant confidence in how your engine feels — crisp throttle response, quieter operation, and stable oil pressure even at redline. The advanced formulation offers exceptional wear protection and thermal stability, so it won’t thin out or break down when the temperatures climb. It’s catalytic converter safe and keeps the gearbox and clutch working together seamlessly.

Why it’ll work for you: Power Synt meets JASO MA2 certification and exceeds top manufacturer requirements, ensuring perfect wet-clutch compatibility and smooth engagement. Whether you’re riding a high-performance street bike or hitting the track, this 5W-40 blend maintains film strength, minimizes friction, and protects every moving part — so your engine stays fast, cool, and reliable every ride.

Ridiculous Price for Mid Quality
Size: 30W x 30L, Color: Khaki
Ridiculous price for such average material. Wrinkles and creases the second you put them on. I got these because they’re the exact color I want and for som reason it’s hard to find.

Defective MK products sold here
Size: 33W x 30L, Color: Khaki
I ordered smoke grey and the seams never lined up. I could not manage to iron these pants. It appears like they are selling the defective MK products on Amazon. Returned mine.

Great watch - looks good and keeps good time
I love this thing. Good for a big wrist. Lume holds well and the blue lume looks awesome with the white/blue theme. Holds writhing a couple seconds (2-5) per day, which is pretty excellent at this price point. Would recommend.
