BONNIE MAINTENANCE:
Triumph Bonneville T100 Torque Settings

I culled these torque settings from the 2012 Hayne’s Service & Repair Manual. What I’m posting applies ONLY to a late model Triumph Bonneville T100 (EFI).

I created this page as an easy way to pull up this data on my smart phone when I’m outside working on the bike. I hope you find it useful also.

A good, fairly inexpensive 3/8″ torque wrench to use if you’re looking for one.

  1. Haven’t

    even

    ridden

    it.

    :-(

    Life and work just get in the way so once all the goodies were installed, I check the sag (30mm – was at 52mm) and parked it. I’m hoping to go for a short put this weekend.

  2. Hey, just dropping a note to say thank you very much for posting this, saved me a lot of faffing about when doing the sprockets!
