Default Cable insulation

Hoping someone can point me in the right direction. Doing a bit of custom work on a bike and have new electrical wires. Running through frame/bars isn't an option, so I'm trying to find some of the plastic "insulation" that you see on exposed wires. Not wire loom, to me that looks cheap, and not the 3M wrap. While that stuff is good, it still looks kind of not good (looks GREAT under the hood of car, but not so much on a bike).

Does anyone know where to get stuff like that? Auto stores are no good, and I'm not having luck hunting things down (that, or my Google-Fu really sucks)

Thanks

We often use shrink tubing. I stick a piece of string on the wires that I tie with aircraft wire lacing string every foot. I then use the air hose and blow the string through the tubing, then pull the wires through and use a heat gun to bind the harness. Works good and looks factory.

Well.... You have to know what you're insulating against, then go after that type of material. I chose 'High temperature and vibration wire loom' and put it in a Google search, here's what I got for you, http://techflex.com/land_hitemp.asp
Maybe your bike sits in places that are below freezing, you might need a loom that won't become brittle under those circumstances. Maybe you live in a zone that's constantly wet or humid so you need a sleeving that won't trap moisture. Does the loom need to be flexible and constantly twist, turn or move? Lots of variables to consider when choosing the correct loom and wire type.

Harbor Freight sells 4' lengths of larger sized shrink sleeve.

Hey guys thanks. These are some good ideas. I will need it to twist and turn a little bit. It will be on the handlebars and along the frame, etc. I just wanted to look as close to factory insulation as possible.

Well if it's on the handlebars then you'll need to also consider the sleeve's rating to ultraviolet exposure. The sun will break down a lot of under-the-hood automotive wire insulating materials real quick. Peruse the techflex.com website and you'll see a whole lot of products that will give you quite an education in this area. And remember too, factory look isn't always better. Harley doesn't want you to keep your bike too long. You're lucky if the exposed factory harness insulation lasts a few years in an outdoor environment before it starts cracking, turns brittle, or oxidizes.

Try these;

http://www.mcmaster.com/ I bought 0.31" ID for 5/16" wire, 25' length for $9.95 part#1508T28 for a 4-wire rear speaker project. It looks like a stock part.
