My friend Tommy G., director of Tenacious
D's music videos, rode his motorbike to a
party in Venice tonight and said it was
quite cold on the way. When I was a teen, I
once seriously burned my leg on the
tailpipe of my little Yamaha 100cc Enduro
at our summer house in Vermont. These
mind
streams collided in to this
halfbakery: use the heat from the exhaust
to warm the driver. While directing the
exhaust gases directly onto the biker
might be the most efficient heat transfer
approach, the toxic properties of the spent
combustion mixture make this a heavily
downsided solution angle.
My idea would be to modify the tubes of
the exhaust pipes to increase their surface
area between the head manifold and the
tail pipes then efficiently channel
airstreams over the hot metal and into the
air space surrounding the driver. The heat
exchanger could be in the space ahead of
the fork beneath the headlamp. The pipe
shape might have a series of S and U
curves or several smaller straight tubes
clustured between pipe sections of a
single larger diameter.
The air intake port will be designed for
maximum temperature gain and minimum
aerodynamic impediment to the
motorcycles operation. The streams of
heated air created by the system should
then be controlled through a subsystem of
hoses and vents to create a more
comfortable environmental envelope for
the driver.
I found other solutions to this same
problem here in Halfbakery but not this
one - I'm new here so I hope it is original
and intriguing.

(+) for mentioning Tenacious D. Not to mention a pretty good idea. |

I'm a rider myself, so I have a couple of things to add. |
|
| |
Coincidentally, I did a ride to Huntington Beach tonight, and it was cold as hell. |
|
| |
Unfortunately, this is already baked. The Honda Gold Wings do have heaters. Also, they make heated hand grips. |
|
| |
The second reason, the main one, is that bikes are all about weight. My CBR929RR is around 420 lbs, and every pound counts. People buy Marchesini wheels for their bikes, at about $1200, just so they can drop TWO pounds. The added weight for the heating system would make any serious rider instantly shy away from it. |
|
| |
I like the idea, unfortunately it is not entirely new or economically viable. I'm going to have to give a fish to this one. |
|
| |
I like this one - if you use the Bernoulli principle, you could use the partial vacuum created by the warm gas flow to power the bike's suction ashtray. [+] |
|

//bikes are all about weight// ..and here I
thought bikes were all about being bad
ass. Shaq's West Coast Chopper Superman
custom looks like it might have some
excessive poundage. This heating system
extends the exhaust pipes, but twist the
tubes right and it could work well and look
cool too. |
|
| |
I guess it works for old man cruisers (AKA Gold Wing) and 80 MPH top speed gaudy choppers (AKA Small Penis Syndrome, *See Lifted Trucks). I don't count those as real bikes though :o). |
|
| |
But because there are people out there that may go mentally insane and buy one of these aforementioned motorcycles, I'll change it back to neutral. |
|
| |
Oh, and Cube, I'll take 180 MPH top speed and cornering through canyons any day over Shaq's bike. To each their own and all that crap I guess. |
|
| |
[DRBC] At 180 MPH, the adrenaline rush
probably negates the need for a heater
anyway. I was thinking of something for
the soft cyclist - and Tommy G. is no two
wheeler light weight! |

Most of the big tourers have heaters of a more traditional make up. (i.e. engine heat taken from the radiator and routed to the operator through the fairings and other bodywork. The main problem I see with this is that it would create drag under the bike where the air is re-directed. Probably not a big deal on an 800lb cruiser or touring bike but a huge deal on a 400lb sport bike. this would be an excellent compliment to the "ski-rack for your motorcycle." [link] |

I think you've got a good halfbaked idea. |
|
| |
anyone who's driven in an aircooled volkswagen knows that the heat generated by the engine, while copious is not really enough to do the job on a cold day and it operates on a similar principal of capturing the heat from the exhaust manifolds. I can't imagine this would help enough to make the extra weight worth it...I think some heated leathers would be a better solution. |

Snowmobile suit. Works on the coldest days, needs no batteries, exotic fuel, or rerouting of exhaust system. Can be found at most stores that carry winter apparel. Best of all, for warm weather riding, you simply leave it at home. |
