I have '17 RM. The hard lowers are nice until the temp gets up into the 90's and above. Having a gutted cat helps, but it is still an air-cooled engine. On really hot days, sitting at a light, you can feel the heat start to build up, and then you can feel it get blown away when you start moving. Once the ambient temps get up over 90, I usually take the lowers off (July and August) unless I am making a long trip.I have a 2017 Chieftain and use soft lowers in colder weather. How do the Indian hard lowers compare? How are they in warmer weather?
