It is difficult to determine which vehicle is "better" between the Can-Am Ryker and the Can-Am Spyder, as both vehicles have their own unique features and capabilities. Both the Ryker and Spyder are popular choices for riders who are looking for a fun and easy-to-ride three-wheeled motorcycle, and both offer a range of models with different performance and features. Ultimately, the choice between the two will depend on the specific needs and preferences of the rider. It is a good idea to research and compare the different models and features of both vehicles to determine which one is the best fit for your needs.
