Product Description

  • This item is considered hazardous material. Orders containing this product will ship ground only and cannot be shipped to Alaska, Hawaii, or US Territories.

Bel-Ray® Works Thumper® Racing Full Synthetic Ester 4T Engine Oil is a 4-stroke synthetic motorcycle racing oil that has been developed for full works competition use and is designed to withstand extreme racing conditions. Full synthetic ester base oils withstand the highest temperatures and stresses which provide the ultimate 4-stroke motorcycle oil. Meets API SM and JASO MA2 requirements. Suitable for air-cooled / liquid-cooled 4-stroke engines and wet clutches.

  • Thumper engines (single cylinder, multi-valve racing engines).
  • For use in all 4-stroke engines requiring an oil meeting the API SG / SH / SJ / SL / SM standards.
  • For use in all 4-stroke motorcycles with or without wet clutches including those specifying the use of a JASO MA / MA1 / MA2 qualified oil.

Bel-Ray® Works Thumper® provides superior anti-wear and reduced cylinder and ring wear for longer bearing life. Its superior deposit control cleans deposits and controls sludge and varnish formation. This also keeps ring lands and grooves free of carbon build-up. The shear stability provides superior lubrication and film strength which minimizes friction for maximum power. Smooth power transfer prevents clutch grabbing for an easily controlled and efficient gear shifting and clutch operation.

The only oil I use.

I ride a 2008 KTM 525xc, and it is pretty picky about the type of oil and amount it has in the engine. It does make a difference. In the past i usually just poured whatever 10w50 i could find in it, and it did its job just fine. This oil, however, stood out immediately. I noticed that my engine runs a little better, smoother, with this oil. It's worth the few extra bucks.
