I read where this is happening....

"A federal judge ruled that a class action lawsuit against Harley Davidson claiming Harley engine run so hot that they pose a constant danger of burning their operators..........."

"The sympathetic arbitrator sided with four bikers claiming their Harley Davidson motorcycles were defective in design..."

If you want the story, I found it here in the forums, .....search the forums for "things-getting-hot-for-harley-davidson-air-colled-engines"

Anyway, I noticed I can touch the cylinder head fins on my Triumph Bonneville America while riding down the highway. Not even hot.

I tried the same on my 2014 Switchback and nearly took the skin off my fingers!!

Why are the oil coolers (on page 564 of the 2015 accessories catalog) an accessory, and not fitted as standard? Is it that we rely soley on the ability of the synthetic oil to be able to withstand the heat, rather than fit an appropriate oil cooler to the bike?

Has anyone out there fit an oil cooler? My America has one as standard - and there are bigger ones on the market if you want better cooling.

I fitted a temp gauge and worked back from there 7 years ago and it runs around 170 to 220 degrees depentend on weather conditions.

Oil needs to be hot to work. If it's not hot enough to burn you, it's not doing its job. Oil coolers in most cases are unnecessary.
