I was picking up an oil filter at the local auto parts store and asked about synthetic oils he had available in 20/50. He has this royal purple in various weights at a good price. Anyone ever heard of it ?

I can tell you without a doubt, that the Royal Purple I put in the gear box & final drive of my '02 BMW made of my bike a BRAND NEW and QUIET machine with less clunking. I think I've heard the stuff is good, but the gear fluid I put in the Beemer..... MAGICAL!

I have been usuing Royal Purple lubricants in both my street bike and Bonneville racer with great success. They are sponsors of the Nish streamliner that has run speeds upwards of 380, a pretty good recomendation. In the racebike I run a 50-50 mix of synthetic and dinosaur oil per the recomendation of my motor guy, Mike Rich. I can't swear that Royal Purple is better that anyone else's synthetic, but it is certaintly as good.

used royal purple for 6 weeks..in 03 speedy ....started having problems with sticky clutch plates...even in neutral had to keep the brake on or it would creep forward....would bang into 1st.
went back to the other syn. i had been using and no problems. royal purple is supose to be good...but did not work for me.

I can't speak to the wet clutch issue, both bikes were Guzzi's with separate tranny's. :???:

Thanks for the info guys, on their web site they have a motorcycle specific oil called max-cycle which might be more wet clutch friendly. Don't know if the "god price" applies to the entire product line. I will go in next week, get some price and avail and advise.
