or the Tutoro

Ryland, something comes to mind, you've apparently not ridden a motorcycle in 35 years and you already want to optimize a motorcycle working very well from stock.

Most of the XTZ owner here have not fitted any performance parts to their XTZ.

You admit yourself (as I do) that you have some gaps in knowledge regarding motorycle mechanics

I'm sorry if I seem intrusive, that is not my point, but i would concentrate on basics (suspension/fork setup, chain maintenance, ...) before trying to get the max out of the XTZ (which will not make a massive difference in the end)

Don't fall for the marketing tricks :)

Ride safe.
