  1. To cut to the chase, I want: * 2 stroke * Powervalve * Water Cooled * Disk brakes * Newer than 1990 * Long Travel Suspension * Trail/Enduro leanings What I have(had...): * 2 stroke * Water cooled * Drum Brakes * 1983 Vintage * Long Travel Suspension * Solid Motocross bike What you need to know. I'm 28, I am 200lbs. I'm not what you'd call experienced, but somehow I've managed to not kill myself on a 1983 RM250 despite only having tight trails to ride on. The ORv park I have to ride at has a small MX track setup, which is fun to putter around on, and lots of technical stuff. I managed to sell my RM250 for a disgusting amount of money. (roughly $900) So at the moment that's my budget. I should have more money for the pot in the coming three weeks. What I want indicates pretty clearly to a KDX200. I really do not want a 4 stroke. But the only bike I know of that fits he bill is the KDX200. KTM makes a 200cc 2 stroke, but the prices on that seem to hover in the $2-3k region. I could probably swing that in the end, but I'd prefer to spend less if I can. I know Suzuki made the RMX250 which was an enduro version of the RM250. Did yamaha make any "modern" 2 stroke enduros? I'm also not vehemently against MX bikes. I'd just prefer something with a power generating stator. To add visual interest. This is what I sold. It's a monster.

    Do it cheap - Do it Street legal?

    Most of my riding is done in a "flowing" aera, so brakes that can stop me faster than hitting a brick wall aren't even close to necessary. The stock brakes are dual leaking shoe drums which actaully have respectable braking power. the bike cost $250. And runs exceedingly well. I couldn't justify the $2500-3000 for a newer bike, and all the supermoto parts. I have NEVER seen an RMX in my aera.
  3. first off, my bike isn't a "thumper." But I had a guy from my GS forum tell me this was the place to go for supermotord intormation. :-) I tend to trust my GS friends, so here I am. Here's the plan. Pick up spare wheels. Preferably from a newer RM than I have. (my bike is "mostly modern" it's a 1983 rm250, so it has a flatslide carb, water cooling, long travel suspention, but the seat doesnt' go up over the tank, and it has drums, and now powervalve) I live somewhere that ridable dirt... well... is next to imposable to find. So the next idea other than just riding the living daylights out of hte bike, was to get it out on the street. The tires I use on my streetbike are available in sizes that will fit the RM. I use Bridgestone BT45's on my streetbike. And RM wheels in stock sizes are cheap and pleantiful. (read $30 shipped on ebay) At least that's the cheapest way I can concieve of getting "good" road tires on the bike. And using a newer RM wheel would get me a disk brake. I happen to have brake master cylinders and calipers I can use on said disk as well. Are the front disk mounts universal? I know that at least the whole of the suzuki sportbikes use the same 5 bolt disk mounting pattern. or am I going to need to get creative with adapter plates? now there's a final problem. Lights. In illinois you need a headlight, taillight, and brake lights. Great, that means the switch setup is simpler. HOWEVER, this is a pure dirtbike. And it doesn't have a "normal" stator setup. Instead of having a magnet swinging around the stator. It has a magnet swinging INSIDE the stator. it also has two coils, so there's really no room to try and suck more power out of that electrical system. Basicly, I need to leave the ignition system intact. The other option is to run a battery. Again, we have this whole chicago-flatlander problem. It's a coupple hour drive to get anywhere worth riding. or a 40 mile drive to get downtown. so this pretty much eliminates the idea of running a total loss electrical system. Also, it gets dark fast in the countryside, so I want a good headlight. drawing 10 amps of headlight is a very quick wayt o kill a battery. *sighs* This means finding some way of generating electrical power. And I think my roomie and I have found a solution. There's a ready made alternator that most geeks have. Stepper motors. Coupple that with two phases of your average, run of the mill regulator rectifier and you have a darned good power source. :-) (testing with a nema 23 size stepper provided 98vac at 1200rpm, this worked out to about 200 watts of electrical power) So for all intents and purposes the electrical system problem is solved. So.. For this lowcost supermoto... $170 for tires $15 for the stepper motor $0 for the R/R (this is a part I have in stock in the house) $40 for the lights $60 for wheels (I would like to keep a set of dirt wheels as well) Registering the bike may be a problem. only "may" becuase I think I can sneak it through under "custom construction" seeing that the bike never was titled in the first place. Has anyone else taken a motocross bike and made it into a street legal supermoto style bike? How have they dealt with the challenges?
