    Gday everyone, looking for opinions on Penrite sae10w40 gear oil for 2012 Fatbob. Penrite recommend it for the transmission, although cannot find many comments of others on the net using it. Cheers

    I have been using this in the primary for a long time now. Penrite Pro Gear 75w85. On the shelf at Supercheap, easy.
    Wee motorcycle logo on the bottle.

    Transmission/ gearbox I have been using Redline Heavy Shock in my personal bike (hard to get by comparison)

    So I keep this now on the shelf for servicing mate's bikes.
    Penrite Pro Gear 80w140. Again easy to get, on the shelf at Supercheap.
    Don't let the naysayers say "too thick", HD started selling a "genuine" 80w140 synthetic gear oil a coupla years back.
    HD oil WAY more expensive than the Penrite oils, only downer is the Penrite come in 2.5 litre bottles, but have a super handy pouring spout.
