Dead on, Steve!
Way cool bike. I had to do a doubletake before I realized it's a Ninja 250. The stickers really do a lot for it.
You said "these bikes will do all I want to do." I couldn't agree more. Mine goes fast enough to get a ticket. How much faster than that do I need to go? Last night I came across this video of a guy doing 300km/hr. That's 180mph!

Clear lenses don't do anything for me. They're interesting, just not for me. I think it's because my bike is red. But on your blue/white/silver bike the clear lenses would look great.
I've seen some flush mounted front lights that I think look pretty good. They're just truck clearance lights mounted onto the Ninja. Everyone has their own taste, but I think that would be good enough for me.
I didn't know my wheels were painted. If so, stripping would be a lot cheaper than chroming, because I could do it myself. It won't be quite as shiny as chrome, but it lets me go on to other projects. I would assume that the wheels are not steel, so I shouldn't have to worry about rust.
My son and I will be riding together more as he gets older, so I really want to get some kind of intercom. Intercoms installed in the helmets would be the best. I might end up with something like the ChatterBox, since noise reduction is pretty important, and it's out of my field to design something like that.
My alternator went out on my car, and my idiot light didn't warn me in time. I replaced the alternator, but I want an ammeter or voltmeter gauge in the car so I can get a little warning next time. All my life I have had cars with idiot lights instead of gauges and I really, really want an ammeter gauge. In this age of digital electronics I could make a digital gauge that is 50 times as precise as the old analog gauges. I worked up a design for the car, and I'm thinking about doing the same thing for the Ninja. I might make it a volt/amp meter, or I might make one meter for each so I can see them both without switching. I'm also planning to install a mechanical analog oil pressure gauge on the Ninja. I can put it in a 1.5" hole that I cut in the fairing beside the other gauges. I think it will look great. A digital gauge would be even better, but more work to design.
I think stainless covers on the mufflers is a great idea. I had thought of painting them with high-temperature paint, but stainless is even better. I'm just looking for ways to make my bike more of an eye-grabber. Changing the black parts to chrome (or similar) will make a lot of difference. Getting chrome visors for the helmets is part of that, too.
