Confidence in the Brand

I have not ridden my GL1800 much since installing it. So far, shifts are smooth, as you would expect. Smooth shifting is my litmus test for motorcycle engine oil.

Awesome selection, service and prices

Great company to do business with! Bought varies OEM parts for my 17 year old Honda VFR. All the items were in stock and reduced at a significant savings. I'll do all my online motorcycle parts and accessories through Motosport!

Value in knowing for sure it's the right stuff

I use this oil in the engine and Belray 80wt on the clutch side of my CRF250. I change the oil about every 3-5 hours, so it never comes out black or even really looking like it needs changed at all. However, using Honda oil gives me that warm fuzzy feeling, and the cost is comparable.

Simply the Best

I’ve been waiting for Honda to make a fully synthetic 4 stroke motor oil for a long time, and finally it’s here. Yay!!! Honda’s been making excellent product and this oil is no exception. Will be ordering more to come.

Can't complain.

It's oil. Not much to review. Buy Honda for the peace of mind.

A: No, Full Synthetic Oil can make your clutch slip. HP trans oil would be recommended. The GN4 would work in both the motor and the transmission.

A: I suggest your owner's manual, and read Honda's recommended applications for this oil. If memory serves me correctly, Honda recommends synthetic blend before 2006.
