I agree, sort of. The cables are much smaller than the typical jumper, but the battery is a lot smaller amperage, too. In an emergency yes, you can safely connect the bike battery to a larger battery for a jump, just don't leave it on there too long and you will be fine. The lower amperage battery will make it charge quicker so that you can start it as soon as possible. A half a minute should do it.

If I was going to go to all that trouble, I'd use 8 ga primary wire at a minimum.

Good thing he's red headed or they would be twice the cost.

I can get some heavier gage wire and find some way to close off the ends so they will not be prone to getting weather or touching the frame but yet I can give a jump to the bat without removing the frame. It can be done,I just have to find the best way to do it. I was just told that I had to remove the shocks at the same time and with the bike jacked up and rear wheel hanging. I did it one side at a time and compressed the shock with a ratchet strap. Worked fine and I had the saddle bag supports on in 15 min each. I just took a few days of pondering.
Ok that's all good you've got the skills to know what the deal is then , I err on the side of caution giving advice in here till I have an idea what level the guy asking is at come on they ask what brand and grade oil to use so I start real low on the skill thing with most .

What I have done on a few hard to get to battery setups , I get a small high amp connector like for golfcarts or forklift battery packs and mount somewhere , on the old bikes I'd bolt it to the bottom of the bat. tray and toss the adapter in the saddlebags .

I have read all the post here on this thread and am a little confused about the consensus. I am going to state that one cannot use the pig tail that came with my battery tender to jump start a bike. The wire is to small to carry the required cranking amps. The best choice is to install a battery tender and the battery will last for years.

I have done it several times in a pinch.

I'm not reading all the posts, you can't use he battery tender pig tails to jump start your bike. The wires are to small to handle the starter load.

This is correct, but you can wire it up to another bike or car and let it the other vehicle charge it for 10 minutes or so, then disconnect the wire and your battery might just have enough juice to start the bike.

Battery tender harness has a 7amp fuse in it. Wishful thinking to use it to jump start.

You can take a SB50 connector and jump start through it.
