Another Linex'd bike


max power

At first I thought you meant "linux", as I recently read an article about an electric bike running Linux. After staring at the pics for about half a minute I went "holy crap...is that freaking Rhino Liner on that dudes tank?" and realized what you were talking about :lol:

No, its Linex on dudes tank.

Same idea :) I don't own a truck and I used to hear Rhino Liner commercials on the radio all the time so that's the first thing that comes to mind when I think of any of those spray-on bed liners.

Meh. I'm not worried about aero.

Cd as measured from the front doesn't hit a lot of what would be "painted" surfaces (part of the nose, the front fender, and a same surface on the side fairing - depending on the bike).

Besides, these fly really well, and that's basically the surface you have - just with less uniformity.

Specific Gravity of Rhino Linings (Polyurethane/polyurea) is listed as 1.06-1.08 g/cc, so for a 1/16" (1.6mm) minimum coating on all the painted surfaces. I have no idea what the actual painted surface area of a bike is (varies anyway), but let's take the dimensions of my SV for instance.

Wheelbase = 1435mm

Height = 1170mm

SWAG'in it... paint covers about 20% of that entire surface area rectangle of wheelbase and height, or about 3357 cm^2.

I figure that's a conservative estimate (no? I dunno), but for shits and giggles, double it, to cover the other side (and we'll already count the fender and front fairing into that final number to be even more conservative)...so we're now at 6714 cm^2. Multiply by 0.16 cm of thickness = 1075 cc's

multiply that by 1.06 g/cc = 1139g.... yielding approximately 2.5lbs of Rhino Lining on a relatively naked bike.

Using the same numbers with paint (Dupont Imron 6000) - lets say you go big with 10 coats at .0025cm/coat, 0.025cm thickness. The paint "theoretically" covers 858 ft^2/gallon (aka 797,108 cm^2/gal), and one gallon weighs 9.54lbs. We have to cover 67,140 cm^2 (10 coats) or 8.4% of that gallon -- or 0.8 lbs of paint.

+/- 10% fudge factor for each for my back of the envelope calculations, rounding error, and assumptions... you're still looking at around 3x the weight for Rhino Lining at minimum recommended thickness vs. paint coated overzealously. And that's for a relatively naked bike - if you Rhino-line vs. paint a fully-faired bike, the added weight of the rhino lining will be even greater.

Alas, you're right - it's not MotoGP, but added weight is added weight. That's why a Lotus doesn't handle like a Caprice.
