Title: Two trends?
Post by zipidachimp on 02/16/16 at 01:55:36

Spent the week-end in Portland Or. at the One Motorcycle Show for cafe' bikes. Found at least 20% of bikes using this unit as a headlight in vertical position:

or the double:

Also, found another 20% of bikes scrapping their master cylinders for short lengths of vinyl tubing(4") connected at the lever and capped at the end with a short air space above the brake fluid. Claimed to be safe? Photos as soon as I unpack my camera. Cheers! 8-)

Those LED light bars are OK for show bikes - but not for one you are going to ride after dark. They just scatter a bunch of light and it won't work as a headlight in the real world. It just doesn't have enough power to shine several hundred feet down the road, and it will blind any oncoming traffic as there is no vertical cutoff or control of the light pattern....it just throws a big wad of light. They really are just "work lights".....good for mounting on your tractor or ATV for when you need to go fix fence after dark. If those fellows ever try to ride down a country road after dark,.....it won't take them long to realize what a mistake they have made with their headlight "fashion" statement.

I have see that brake fluid tubing trick on a bike in a show last year. As long as your pads don't wear and you monitor the level....I suppose it works. It doesn't have the ability to compensate for pad wear - so you have to keep an eye on the fluid and keep the tube topped up.......and be ready to catch the fluid that spills out if you spread the caliper to install new pads. I can't see that installing a small reservoir someplace would detract from the "curb appeal" of the bike.

The tube idea has been around for donkeys years. Its not uncommon on track bikes and streetfighters to replace a remote reservoir that got broken. Completely safe and no problem.

This was the first time I saw both of these items. Another example of 'form over function'. Amazing how these things catch on. With good luck, they'll stay on the show circuit, not the street.

Those lights or ones similar are becoming popular in the F150 truck forum for replacing the "fog lights" on the trucks.

Isn't there a piston in the master cylinder to push the brake fluid through? Without it you just have gravity pulling the fluid through. Someone educate me on this. It doesn't sound safe at all to me but I know as much about this as I do brain surgery!

the orange bike is a 2015 duc scrambler with a grafted on rear section, and handmade tank, lovely workmanship.

Think of it in this context, appropriately Americanised :P: The master cylinder is a hopper, where you might pour a pile of bullets (or brake fluid). The master cylinder piston is the breech of your machine gun. The piston takes fluid (or bullets) from the hopper and pumps (or shoots) them down the brake line (or barrel). While the bullets arene't needed they just sit there in the hopper, waiting their turn. Difference being, with a brake, more bullets only come out to compensate for the brake pads wearing. So, you really only need a small amount of fluid waiting upstream of the master cylinder. I wonder if that makes any sense at all?

Edit: just looked at the pic of the scrambler: It's a radial master cylinder so a bit different execution but the idea's the same.

the bikes still have a 'master cylinder' just not a reservoir
safe until the pads wear, then you gotta add fluid manually, whereas with a standard MC with reservoir, the fluid is added automagically
