Bel-RayThumper Racing Full Synthetic 4-Stroke Motor Oil 10W-50 4 Liter

This stuff isn’t cheap but has always kept my Husqvarna motorcycles running strong.

Best oil out there. Handles heat very well.

I ran Bel-Ray MC-1 in my 2 strokes back in the late 70's & early 80's and Had GREAT Results! less wear & longer times between re-rings & a piston would last all season, now that I have a Yamaha YZ 250F 4-Stroke I turn to Bel-rays Remarkable Lubes for its needs ,say what you want but Bel-Ray Thumper Racing Full Synthetic 4-Stroke is all I'll trust my Engine to. 5 STARS PLUS!!!

Best 4 stroke oil hands down. Huge difference compared to Maxima Extra 4, and Motorex Cross Power. Shifts smoother and feels slick much longer than the other full esters I've used. Expensive? Yes, but I feel it's worth it.

Bel ray all the way on ktm and husquvarna bikes

Exactly what I needed

Its oil and good oil at that! Going in my husqvarna!

Perfect replacement
