Pillion Heat

[ravenrider]

Morning Guys,

My wife finds the heat emitted by the exhaust makes riding uncomfortable. This complaint has been since day one and it didn't help that I switched the OEM exhaust for a Wasp. Anyone else hearing similar comments? I'm trying to come up with some sort of shield to deflect the exhaust without killing the appearance of the bike.

Thanks for any comments/suggestions.

Bets regards,
Wayne

Are you sure it is not actually the hot air exiting the rad on the left side?

I was riding in the heat the other day and hung my left arm out and was pretty shocked at how large the hot air blast area was.

Maybe the air is coming back toward the bike and hitting the passenger?

Just a thought.

Just curious - did you take off the stock heat shield as well?

 

[Cykel]

My wife commented that her left foot gets very hot due to the heating of at the base of the exhaust shield there. Her boot is very warm to the touch after a ride.

I have yet to play around with any solution, but I'm interested in people's thoughts myself ::017::

Thanks for the comments,

Andy,
Rad air may be contributing but the left hand rail, left bottom/left side of the OEM top trunk and left rear directional are all hot after a ride.

Koinz,
I left the stock heat shield in place.

I'm looking into the possibility of fabricating some sort of an extension for the stock heat shield that will cover the portion of muffler extending beyond the stock shield and closing off the area below the hand rail.

Thanks,
Wayne

My wife complains about the same heat problem. With a little experimentation while riding, I determined that the heat was indeed coming from the radiator and not the exhaust. She describes it as short burst of heat. It comes out the left side, goes around my leg, and depending on wind and turbulence, hits my wife's left leg. I have stock exhaust and it is well insulated by the guard. I felt no heat emanating from it. I am considering fabricating some sort of deflector, but making look like it belongs on the bike may be difficult.

Two plausible solutions:

1) elected amputation of left leg. I would recommend a couple inches above the knee. they are making some cool bionic knees nowadays

2) ride her own bike


Just thought you should not leave out any options 8)



In all cereal-ness, my wife has not complained about heat on the left side. Though our rides usually encompass a stop every 30-45 minutes.

My wife just did 4400 miles on the back of ours and did not complain. It was 106 degrees at times.

I actually mentioned the left side heat to her on the trip. She concurred that she felt it, but it wasn't a big deal.

What kind of pants was she wearing? My wife was wearing mesh overpants with shorts underneath.

 

[bloodline]

Gaerne women's boots that zip up and rev it Ventura pants with Klim underwear shorts thingies.

Get her some non-mesh pants and some LDComfort shorts or tights. And tell her not to wear street clothes under her riding gear.

Mesh lets heat in. She needs some insulation from the heat.

I'm not so sure about that mesh letting the heat in thing. We both have non-mesh riding gear, but when the temps get above the mid 80's the non-mesh gear get unbearable and the mesh goes on. Maybe it's different in Utah, but here in Georgia the air gets a bit thick in the summer.

 

[EricV]

It is a bit different in Utah, evaporative cooling works here, not so much in Georgia. But, LDComfort under garments work. Keeps the moisture off your skin and wicks it away. The common technique of wetting down, doesn't really work in high humidity conditions. Still, eliminating the street clothes layer and the mesh will help, imho. I've ridden in plenty of the South and know well what that is like. I didn't zip up as much, but did keep the non-mesh on and the LDComfort works to wick the moisture away and cool with the air flow. Too much air flow, (mesh), and you're simply letting the hot air in and bleeding out more of your fluids, leading to dehydration and discomfort.

The bonus to the non-mesh in this case is insulation from the bike's heat. LDComfot tights and non-mesh pants will make a huge difference in how 'hot' she feels. I know it sounds counter-intuitive, but it works.

I never use the pillion seat so I thought this thread was gonna have a pic of a hot chick in a bikini on back of a Super Ten.

 

[snakebitten]

That's hilarious.
And a fair expectation considering some of the characters on this site.

Hello, here in the tropics I have the same problem (excess heat in the left leg).
Me and my wife felt the same. It comes from the engine radiator (left side).
We do not believe it is due to the exhaust.
So I tought in two possible solutions:
1 - A baffle for the hot air flux coming from the fan.
2 - A thermal blanket placed inside the fairing.

Maybe I use the two solutions together, still not sure. I need to check it.

What do you think?

 

[coastie]

This has always baffled me! I have tried to simulate this in the heat of summer in Texas with no luck. The only way is if I wear jeans and slide my leg up as tight as I can where it vents on the left side, but the motorcycle has to be super hot with the fan on. No idea how the passenger feels it. Sorry I can't help you, hope you figure it out.

I think you're not wearing proper riding gear. Or riding slowly in traffic.

No harm in re-directing the air from the fan or trying the thermal blanket. Hope it makes you more comfortable.

I found out the hard way that mesh pants shred like confetti if you slide down the road in them. No way would I let my wife wear them....


Bought a pair of LDC tights and shirt, wore them in late Sept. in 28C weather and found them to be oppressively hot. They are nice now that it's winter though....

 

[creggur]

Cycle Gear Heat-Out shorts and Tee (think I paid $20 for the set) under Klim Lattitude setup with all the vents open for summer riding here in the south worked-a-charm.

Was it warm? Yeah, there's no way not to be down here in the summer even without protective gear, but it wasn't anywhere near unbearable. The only time it gets bad is in stop-n-go traffic. Wife wears perforated leather and hasn't complained (much) about the heat, and none at all about heat coming off the bike...

The twin cans under the rear seat of the VFR couple with radiators on both sides with the airflow aimed straight at the rider from those things (it seemed) made for some miserable summer riding. The Tenere is air-conditioned in comparison....
