Best dual sport bike for the street?

[Dusman]

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 can't help but think that if you consider how much work is actually done for the amount of fuel consumed, they are all incredibly inefficient. Is that a fair statement?

Not sure to what you'd compare it to.
If you compare it to a roketa mc 05 127, or a Grom, both getting well over 100mpg, any bike will look poor in comparison. The first bike being geared very aggressively for higher mpg/lower rpm per mph.

The Vader 150 is quite poor in it's gas mileage. Granted, I ride it at 6k rpm most of the time, and get a solid 60mpg out of it, while it gets closer to 80mpg when keeping it between 3 and 5k rpm.
This engine should be able to do 100mpg easily at 40-45mph (doing ~ 4k rpm.
A lot of the China bikes have lower performance when they're:
a- Air cooled, and,
b- not fuel injected.

Mainly because they'll run a pretty low compression ratio.
If there was only an easy way to increase compression ratio on pushrod engines... Especially people in colder regions will benefit from this (higher gas mileage, same or better performance).

Seems like another contender (5spd) is the magician 250.

there are reports of 100cc bikes in India getting 100kmpl/235mpg.


But that's India. I can't say the models off the top of my head but that 100cc segment is cutthroat over there...


You would not be going particularity fast by western standards.

Yeah. First. Like with a lot Asian, numbers need to be taken with a grain of salt. Second, they're probably in British mpg, which is like 33% higher rated.
A 4 stroke carbureted bike, ideally reaches up to 120, and that's with heavy overgearing. Fuel injected bikes can reach up to 150mpg, because they can lean out the mixture so much when power isn't needed and load is low.
So, reaching 200+mpg, may be possible on a mountain trail downhill.

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…

Ok since no response I assume it’s the problems that I’ve seen on YouTube about this bike. Shucks this looked like it would be a great bike

Orion Powersports RXB 190L Long boring pissy rant, on You Tube from Joe B. is what I was thinking when I posted.

Seems decent enough. There are some quirks with the ZS190 that should be addressed.


The starter chain is typically shipped dry and can snap.


The shift star cog has a habit of popping off and should be looked at.



But otherwise seems like on ok 'big pitbike' for the street.


I would look for a vertical engine frame alternative though as this will open up far more engine upgrade options...


horizontal engines have their place...So if its a platform you prefer then realize the zs190 is about the peak with racing options squeezing a little more...

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.

The Templar X and Trailmaster TM38 (non-EX) fit JTR210 sprockets. Maybe yours as well. Here is the info:

You can see if this matches the boltpattern on your EX.
