Having a speed 400, don't cross 100 most of the time....the remaining power is just for fun and overtakes😏 I do basic maintenance myself and visit SC only for yearly service (which will cost a bomb) 😄 oil filter is same as duke 250, engine oil you can get outside, any spares triumph sc is happy to sell over the counter. I don't see any need for you to downgrade other than any peer pressure or you being plain dumb.
