possibly a patent issue. weight, cost $$. Honda able to developed it since they have use the DCT on other vehicles not just on bikes. it has been around before thy put it on a bike. i call my DCT AT a “matured rider’s bike” also like the manual tranny and have other bikes that i ride and enjoy for that reason. unfortunately, my Husqvarna 701 got me stranded 500 miles from home in the middle of the desert due to a clutch slave cylinder failure (known issue) but i assumed it wont happen on a brand new bike.
