Here we go again. Forgive my tone if it sounds judgmental or condescending. That is NOT my intention. I'm trying to offer practical advice in a practical and straightforward way.

-- The 250r is good for atleast 50k miles before needing any kind of overhaul or internal engine work. Valves rarely go out of spec, but it's smart to check them at the recommended intervals.

-- The 250r can ping off the rev limiter in any gear for years of riding without causing it any harm. Don't think in any way/shape-or-form that you are somehow preserving the bike by not taking it to redline.

-- People can push a 250r on a track for years without being able to ride the bike "to it's limit." I'd focus on improving your skill as a rider instead of buying something with more power.

--- The notion of putting 4k into a bike that can be bought on CL with under 5k miles for 2k or a little more is asinine. Repeat after me... "I will never get that money back." In all seriousness you're better off spending that 4k in a casino because the money is as good as gone as soon as you click "place order" and buy the parts.

-- I don't think a 150 rear tire will fit. I've been through 4 140 rears in the past few years and there's not much room between the swing arm and 140 edges.

If that 4k is really burning a hole in your pocket, buy another different type of motorcycle and learn how to ride it. Cheap dirtbikes will do wonders to improve your skill as a rider.

Better yet, put it into an investment which will hold [some] of it's value better than a motorcycle. You can travel for a long time with 4k, and travel is a great way to improve your character/outlook as a person.

Good luck with whatever you choose.
