The press intro took place in Park City, Utah, at an average altitude above 6000 feet, making it diffi cult to gauge any increase in power. The Switchback felt as strong as any TC96 we've ridden recently, however, so we'd expect that increase to be more apparent at lower elevations. Like all recent Big Twins, the TC103 runs fl awlessly-even at altitude there were no hiccups-though the bigger motor does have a more pronounced character. Larger pistons and higher compression create more noticeable engine braking, so the new engine doesn't seem as transparent as the TC96. The TC103 also seems to throw off slightly more heat, mostly radiating off the primary cover on the left and the rear header on the right. You barely notice the stiffer clutch pull-Harley says effort has only increased from 15 to 17 lbs.-but neutral is almost impossible to locate in the six-speed Cruise Drive transmission. Hopefully, this will improve after more break-in miles.
