2018 Speed Twin Service Manual

Hi Roger,
Haynes manual number 6401 covers the water-cooled twins including the Speed Twins from 2016 - 2019, so will include your bike. There is a wiring diagram in the manual covering the Speed Twin.

I have an unmarked copy of the manual as it also covered the Street Twin, which I previously owned. If you are interested send me a PM and make an offer, you could either collect or I'll post it to you.

 

Hi Roger, I attach a couple of photos of the manual, it states on the spine 'water-cooled twins 16-19' and in the list of models the Speed Twin of 2019.
In the narrative inside it states that the Speed Twin was a new model for 2019! Perhaps they mean model year 2019 which normally starts mid - late in the previous year, ie 2018.
Photos attached

Thought it was only the Americans which date things a year in advance. I'd expect a 2019 Speed Twin to be the one first available at beginning of 2019. (And the Americans would call that the 2020 model). Doing a quick Google gets a video dated December 2018 of the ''new 2019 Speed Twin launch evening'.

Side note, I used to get an American monthly magazine and the cover date was 9 months in advance, so edition shipped in January would be dated September, bugged the hell out of me.
