It's time to replace the original, 5 year old tires on my 2013 SE. I'm probably going to stick with Dunlop, except I'll be opting for the Roadsmart 3's this time. It should be a better overall tire for the riding and the roads in Northern California. However, when using the bike/tire match feature on the Dunlop site, they do not recommend the Roadsmart tire for a Norton, only the Sportmax Q3+ and the GPR 300. Anybody have any ideas why that would be?
