can i Jump start my 2017 DCT

My battery has run flat (yes, I know I don't use her enough) and instead of removing there battery, which is a nightmare, is there any other safe way of jump starting the bike.....

You don't have to remove the battery to jump start.
Just remove the toolbox and open the cover to get at the terminals.
That's as easy as it gets, unless your battery has discharged completely.

You can jump start lithium? I was told not to, but I'm not convinced they knew what was up.

I had the same issue in February (no electric in my garage and the bike had stood for 6 or 7 weeks) I faffed about taking the battery out and charged it whilst putting a charged spare in its place ( I figured that at some point in the future, I'd need to get the bike started to catch a ferry or something and be stuffed if it wouldn't start, so bought a 2nd battery I keep in the house fully charged) I can now swap the battery in less than 5 minutes...it's just getting used to it and knowing the correct spanner that'll fit for the left hand side 'awkward' terminal.

I don't believe you can.

I have a lithium battery too. Do yourself a favor, buy a Battery Tender Junior 800. Gives you the option to charge lithium or lead acid battery.

Love it!

It depends. If the cells has been detached by the management system before going too low (let's say around 2V) , then it can be recharged and therefore jump start the bike. If the cells has been completely depleted (<1V), then recharging them would be dangerous. In this case the battery is simply waste.

I have pre-empted this, because for me it may not only become a problem caused by not having ridden the bike for a few weeks. I'm away working a lot, so my DCT sits on a battery maintainer anyway.

What happens if you are on a trip, alone, miles from anywhere. You've camped out overnight. In the morning you hit the start button... clunk, click, click click. Nada!!
On checking, battery terminals are tight but the battery is flat. You are stuffed! Even more so if you are out of cell tower range and don't have a Garmin Explorer GPS comms unit (or similar). I have one, but that's not relevant here.

It's a DCT, even if you had a down hill stretch you can't bump start it, as the engine needs to be running for a clutch to engage in any gear.
Besides, even it were manual, on flat ground no single person will be able to push and bump start an Africa Twin.

My solution was to pre fit and run a jumpstart lead up under the front seat. It's a heavy duty cable permanently connected to the battery. Under the seat it terminates in a connector that I can simply plug into my Lithium jump start battery pack (that also has USB charging ports and a torch - flashlight in USA speak).

I carry the pack with me at all times as it also has crock clips and can be used to jump cars and other bikes, good Samaritan style

So, if I ever need to jump start my DCT, at home, in town or out in the boonies, I just lift the front seat, plug in and start. No need to pull any covers off or slide the battery out, which in my case also entails removing the left RockFox upper crash bar!

What a smashing idea. I have a fuse block under the seat. It probably wouldn't be that hard to jump the lead (I have a similar lithium battery jumper) but time will tell.

what does the owners manual say? Because mine says "Do not Jump-Start..." This is on page 167 of the 2018 owners manual.

So, is this specific to Lithium Battery/ride by wire bikes?
