Don't make the mistake of comparing auto oil change intervals with motorcycles. Many motorcycles including the Spyder have a wet clutch which increases the rate of oil shearing. Large molecules which control viscosity are permanently sheared over time causing the oil to lose the required viscosity needed to protect engine components.
Extending oil change intervals is false economy. Stick to 3,000 miles for the Spyder.
This is a misconception and bad information, as pointed out by Bad Dog6 But then the question must be asked, 'Can you get good information from a Bad Dog?' :dontknow: Oh well, maybe that question can be answered in another thread!

I do agree that if you are using a standard or a 'Synthetic' oil that is not a true synthetic (BRP's 'Full Synthetic' and most other brands for example), then yes, you should probably stick to the 3,000 mi oil change interval.
It is a shame that marketing of 'Synthetic' oils has muddied the waters and intentionally made the subject confusing to the consumer. The truth is, all Synthetic oils are nowhere near the same thing. There is a world of difference and protection capabilities between fake 'Synthetic' and true Synthetic oils.
I am an Amsoil fan because Amsoil is the real deal and they deliver. If they ever stop living up to their claims I will no longer be a fan. In other words, my relationship with Amsoil is performanced based, period.
So, the rest of the story is, with a Class IV, Ester based true synthetic oil like Amsoil (and a few others) doubling the mileage change interval will still give you better protection than changing oil in your Spyder every 3,000 miles. This is due, in part, to the fact that the molicules do not break down, as in other oils, even with the crushing forces encounted with transmission gears. This is not hype, rumor or hearsay. It is documented in several independent tests over many years, both in the labratory and in real world conditions.
Now I am not saying that everyone has to get Amsoil, or another true synthetic, and extend your oil changes to twice the mileage. All I am saying is the option is out there and it is a viable one. You get better protection for less money and 1/2 the effort. Sounds great to me!
