I burned my calf in 1979 on my Honda 360's exhaust pipe, so basically if I had a HD back then it wouldn't have happened since they only got hot after 1999.
Like I stated earlier, anybody that rides and doesn't know the exhaust is hot shouldn't be riding. I lost count a long time ago of how many times I burned my legs on the exhaust pipe. Buyer beware is exactly the whole enchilada.I have a stock 04 RK with no heat issues. Apparently starting in 07 Harley had to lean the fuel mixture to meet California EPA regs, and they also increased the cubic inches that year too. These two factors created excessive heat issues. Most buyers modified the exhaust and remapped the fuel mixture to solve the problem. The problem was more pronnounced on touring bikes with lowers and fairings that restricted air flow to the engine.
For riders in warm climates the bikes were too hot to ride without doing the after market mods. I believe Harley knew that touring bikes sold in warm climates would cause many riders to be dissatisfied. They should have disclosed this info to buyers at the time of purchase, apparently they did not.
These are the only people I have head of getting actually BURNED from the heat put off by their air cooled engine with a twinkie. Friend has a CVO Road Glide Ultra with a 110. Runs SUPER hot. He hasn't had burns from itAlthough I may be mistaken but, it would seem a few people are missing the key argument here. I don't believe it's merely the pipes or engine metals being hot to the touch but, rather the engine itself is putting out an exuberant amount of heat to such an extent that it's burning people. There was a dude (Phil Magee) who commented within the link that says he owns an '04 Electra Glide and has had his jeans burnt from the ambient heat of the engine - not by touching it. I'm sure most of you can relate to a similar feeling of heat protruding from the engine while riding, thankfully it's pretty minimal since our bikes are liquid cooled.
While I'm a bit on the fence in this case as, perhaps HD should have warned people, it also seems like the alleged "bikers" are wusses and, they should have probably realized this after test riding the bike before making a purchase.
