Bel-Ray unveils new synthetic oil for touring, sport bikes

With summer riding season in full swing, Bel-Ray is helping motorcycles perform at their best with EXS Synthetic Ester 4T Engine Oil, the brand’s highest performing synthetic engine oil for multi-cylinder touring, sport and racing motorcycles.

Bel-Ray’s EXS Synthetic Ester 4T Engine Oil provides unmatched performance and protection in four-stroke race, sport and touring motorcycles both on the street and at the track.

Engineered for unmatched protection and performance both at the track and on the street, Bel-Ray’s EXS Synthetic Ester 4T Engine Oil features a high viscosity stability to provide maximum lubrication under the stresses of high temperatures and RPMs, when engines are most susceptible to friction and wear. A proprietary additive package provides further anti-wear protection under all conditions, helping reduce cylinder and piston ring wear as well as extend bearing life.

Engine performance is also maximized through EXS’ superior deposit control. The synthetic ester engine oil is formulated to clean and prevent deposits known to reduce engine horsepower and torque, including carbon build-up in piston ring lands and grooves as well as sludge and varnish formation.

In addition to maximizing power, EXS Synthetic Ester 4T Engine Oil also provides smoother power transfer in applications that utilize a wet clutch. Bel-Ray’s formulation prevents harsh clutch grabbing and jerky engagement, providing more efficient and controlled clutch operation and gear changes.

“We developed EXS Synthetic Ester Engine Oil to be our best street engine oil at the time, and it still continues to be the best today,” said Andrew Hodges, Bel-Ray’s R&D product line manager. “No other oil on the market offers this same level of performance and protection in such a wide range of conditions — from prolonged high rpm racing to every day stop and go riding.”

Bel-Ray EXS Synthetic Ester 4T Engine Oil is suited for use in all air and liquid cooled four stroke engines requiring an oil meeting API SG/SH/SJ/SL/SM standards, including motorcycles with or without wet clutches specifying a JASO MA/MA2 qualified oil. EXS is available in four different viscosities — 5W-40, 10W-40, 10W-50 and 15W-50 — in both one- and four-liter bottles.
