Spectro has a additive package designed for 6 speed

Re: spectro vs MOBIL 1

Six speeds have helical gears in first and fifth and as such need a different additive package to protect against the thrust that is created by the gears as opposed to the 5 speeds that have straight cut gears.

Re: spectro vs MOBIL 1

Can't say I know the details, but I listened to the advice here and once I switched to Spectro, I was a believer. No longer is it hard to shift into neutral and no longer does the bike stick in Neutral when shifting to 2nd, a problem I had on occassion before. One change is all you need.

Re: spectro vs MOBIL 1

well i used regular old rev-tech gear oil since i bought my bike new
and the last oil change i switched to MOBIL 1 gear oil
now my tranny never got hung or mad noise with the rev-tech
only thing i noticed was smoother shifting when i put the MOBIL 1 in
my tranny is a 5speed

Re: spectro vs MOBIL 1

Try the spectro GL1 which is for 5 speeds and get that engine oil out of the trans.

You'll see a world of difference.

I have used Harley Primary oil, Spectro, Bel Ray and now I just use cheap 85w90 Gear Oil, never noticed any difference. Just pulled gearset out and it looks fine at 115,000 miles.
