Yes I am confused between Harley Davidson 750 street and kawasaki walcan, please tell me which bike is best on mountains as well as plain?

Both bikes have their own forte. If you are looking for comfortable feature loaded car with amazing performance and features, the Harley Davidson 750 seems like a better option as it provides a better punch and belt drivability makes the transmission of the power linear and low maintenance. However, the Vulcan S comes features loaded which makes it an amazing pick in terms of utility. Moreover, the bike also gets Monoshock suspension for the stiffer rides. If the Harly Davidson is compared, the Davidson manages to get twin shock absorbers at the rear for better performance. ​ Moreover, we would suggest you to visit the nearest dealership to take a test ride of both the bikes so that you may evaluate the performance, design, and comfort of the bikes.
