Best dual sport bike for the street?

I did change tires from the MX only to a pair of Tusk dual sport tires and love them. I have the part number but can find no one who can order it.

Rebel gears makes custom sprockets. Just have your OEM sprocket dimensions, or send it to them, and they will make one with the desired tooth count.
4 tooth isn't going to make a noticeable difference quite often
I myself would swap a 51t with something like a 35 if it would fit.
Check the bolt diameter, and swingarm clearance. Then go as small as you can go.

For a 250 to do 60mph it needs to rev below 6k rpm in 4th or 5th (second last gear). That way you'll have top speed in this gear, and 15mph lower than peak speed in final gear (good for suburbs, and good in fuel economy).

The Orion RXB 190L is about as close as you can get to what you’re looking for, but again, it’s the 5 speed ZS190 engine, not a 6 speed. It’s street legal and powerful (@ 16HP stock; some say 18) and only 178lbs, but again, it’s street legal pit bike with a dirt bike seat and essentially what is a racing engine. ZS190 engines are known to be higher maintenance and finicky (i.e., starter chains breaking).

I was looking at this bike too. It seems very nice and by the pictures I’ve seen the seat looks more cushy? My problem is it’s coming from a Texas dealer but says they state on the mco motorcycle. They might be a more powerful, more comfortable bike that looks like our Storm 150 DLX. And I noticed the seat height is lower. Why isn’t it the big seller? Would be curious to hear from others about that higher maintenance problem! I know a bit more expensive too. My thoughts…

A buddy of mine has the previous RXB150L. The MCO did indeed say "motorcycle." It should theoretically be street legal but my state gave him some static over not coming with a chain guard from the factory and it also arrived without a license plate mount or plate light, both of which we had to fabricate. That wasn't too tough.


The seat is a plank. You may as well ride it standing up, or you should invest in a pair of those padded undershorts for bicyclists.


The reason it's not a big seller is probably because, for the 150 at least, it is comically tiny for adult riders and is also geared/powered so that it maxes out at a screaming 45 MPH. It is also very squirrely on pavement above 40. It is not fast enough to be safe to ride on anything but neighborhood streets in wide swathes of the US, where if you are not capable of doing 65+ MPH at the drop of a hat you will be run over or blown into the weeds by a raging Karen in an Escalade.
