Castrol 06114 Power 1 Racing 4T Motorcycle Oil - 10W50-1qt.

It is oil, it meets my motorcycle's needs, what more can you ask for?

If you drive a European car or motorcycle, Castrol offers the best product on the market for your vehicle. Both synthetic and regular it is unbeatable.

Awesome stuff. Hard to find in store.

Meets the specification requirements of my Can Am ATV's. Although my machines do not have a wet clutch like a motorcycle and per the manual, they could also use an SAE motor oil, it gives me a little piece of mind to use the manufactures preferred oil spec. The quality of oils are certified through testing and any comments regarding how well it works would be totally subjective but that said, this is a good oil and the price was right.

Makes my 18 year old 171,000 mile Suzuki M 109 run like new. Smooth shifts. No oil usage in 3000 miles.

I have been using this product for several years. Price is better than other brand KTM recommends. Easier to obtain also. Quality oil.

Bikes love it

I have used this oil in a C10 for two oil changes so far, and have had good results. I can’t honestly say that I experienced noticeable performance gains, but I have ridden long, and fast, in the heat of summer with no mechanical problems. Gears shift smoothly, and I am able to stretch oil change intervals. My only complaint is that the 10-50 is only available on Amazon.

Competitive price and convenient to have it delivered at the door

good value
