Street Triple RS New or Built 2017

Hello, I would like to get a Street Triple RS 765 for next summer. I have found on mobile now 2-3 in my vicinity with Km stands under 10 tkm. With little extra equipment the so lie between 9 t€ -9,5t€. The first “new” (2018 he with 0 KM) so lie at 10,5-11 t€. If it is worth taking a used one because of 1000 € or would you rather take a new one, because I find a discount of 10 – 15 % not so much for a “year machine”. Know this only of cars, and There the tee is much bigger (percentual). To me: I am now 50, children are grown up, than the typical re-enterer. I have always driven moped from 14 😉 to about 25. Then because of work and family convertible and now I want to cruise with a few friends a little cozy. Would be happy about all tips and tricks. Greeting and many thanks
