Old thread, yeah, I know (but then this forum is a tad slow
)
I have a 2020 TXT300, and I've thought the exact same thing. Dealer only had 300s, and had sold the only 280 they were alloted. So home came the 300.
I also had the idea, hey, just get a complete top end, right?! Till I saw the price! I guess a more progressive throttle tube and more/longer learning period it will be!
