i used Redline heavy shock proof in my big twin & that's the best i have ever had, was only gear box oil that made my gear box feel a lot better shifting.

BUT we CAN'T USE THAT IN SPORTY.

i've had penrite gear box oil in and was sticking clutch plates, made clutch feel like crap!!

used the old Harley sporty oil for primary & trans was ok, used Harley Formula was ok, used Redline MT was the best i've used in sporty ( still have it in tube frame Buell, just road past two days for few hours with  the BelRay Sport ( looks like ATF ) i can't feel an improvement like i can with the Redline MT. my problem is i can't seem to be able to find redline MT for sale. shop i used to buy from said they can't get it now.

So what do others use and can you notice improved feel when shifting gear?
