Have you ever ridden a bike before? I've offered to let a few obese people sit on my bike before, and they've all refused because they didn't feel like they were physically capable of getting their leg onto it. My bike (CB500X) isn't particularly tall either. Have a sit on a few in the shop, but you might want to focus on cruisers for their low seat height.

>can a Ninja 250 go on 65-75 mph roads and keep up with/pass traffic with a fatfuck on it?
Consider the fact that the bike is designed to be ridden with a pillion passenger. It probably has a combined maximum load rating of around 170-180kg, so you're fine in that sense. But that said, a Ninja 250 wouldn't be appropriate for those roads even with a healthy-weight rider. I owned a Ninja 250 for 4 years, and I weighed about 80kg at the time. It's great at 80km/hr, uncomfortable at 100km/hr, and spending more than a few minutes at 110km/hr literally killed my ass.

I see 125cc scooters riding with pillions all the time. You *probably* aren't too obese for a Ninja 250, but you shouldn't expect to maintain freeway speeds on a beginner bike. Bikes in general have far lower top speeds than cars. One thing to consider is that bikes have adjustable spring preload, so you'll want to crank that up a bit before you ride or it will be far too squishy. It usually takes a special tool and it's a bit tricky to do, but you'll only need to do it once.

If you want the ability to go on an interstate, which is presumably incredibly fast given usual American standards, you'll want at least a 500cc (Rebel 500, Eliminator 500, 450 CL-C). Maybe even consider a 650cc (Vulcan 650). But once you actually ride a bike, you'll probably quickly realise that you don't actually want to go at those speeds for quite a while. It's a very different sensation to a car.

Also I just want to say that I get physically repulsed by obese people, and I genuinely believe in your ability to fix your situation before it's too late. Good luck.
