I've do 70 to 75 GPS bike registers 78 mph but I am running a 110/100/17/8 front and a 150/70/17 rear shinkos 705total weight is over 360 lbs two people on it flat ground no wind but I average 50 mpg only and RPM never go above 8,000 no power to pass or stong head wind won't do over 70 mph but I love my 2017 RX3 china BLUE 12,0000.0 miles trouble free

I've got a speedo corrector, before that it was reading a little more than 10% over real speed. I've got a 100/90-19 front tire. My "highway" usage is still just around town, I'd never consider a long ride on this thing. Our traffic tends to flow around 70 most of the time, and I can keep up with that easily. It will give a little more as needed. I'm also running one tooth down in front, that's almost a must-do, especially with a little altitude. We're only around 1500 feet, and it's a noticeable change from sea level where I bought it and first rode it.

Even if you can hold the speeds you’re looking for, perhaps with a big bore for example, the RX3 is too light to be comfortable on the highway for anything more than short stretches, IMO. Lack of power combined with the lightweight, should have you looking for a bigger bike. It wouldn’t be a consideration for me. Especially in my case at high altitude with long sustained hills, strong winds and 80mph speed zones.

100jmph or 65 miles per hour long term is the absolute limit for this engine
If that’s what you need to do it’s not the right bike
It’s a light low cost adv style bike
Not true adv not true speed limit bike as such
Still for me in china this is plenty in this crazy world

My longest ride on the RX3 was about 90 minutes at 70-75 the whole time, and I was done for. As a comparison, on my CBR1100XX I would routinely do ten hour days. Maybe I'm a sissy, but this will never be a road bike for me.

Well, the 8000rpm book by joe berk says they'll do highway though. I dunno, I guess I'll have to actually ride one to see if it'll be acceptable.

Charles.

Yes, they will; and yes, you'll definitely need to ride one to see if it works for you, considering your speed criteria for highway use.

Personally, I find it capable of highway use, but I ride sedately, without needing to pass everyone in front of me. I pick a speed and stick to it; usually between 55-65 MPH, with little to no passing. I don't have a problem staying in the right lane on multi-lane highways with higher speed limits. If you want or need to ride faster than that, my original recommendation of a bigger bike stands. As to the weight and how it relates to comfort, I find the RX3 to be a lot more comfortable than my 100+ lb. lighter TT250, which in itself is a surprisingly comfortable bike. It has enough weight not to be pushed around by crosswinds and vehicle wind blast as much as a lighter bike, although it is not in the same class as my 1990 Gold Wing at 900 lbs. or so.

Still, it holds it own it own in 55-65 MPH traffic. Above that, a bike with a twin cylinder engine, either parallel or V, is what you should be considering.

Riding 55-65 on highways here will get you killed. So that part varies by location I guess.

I couldn't agree more. Short stints is one thing but it seems that "we in general" are always looking to make a little, lightweight 250 do more than it was really made to do. If freeway is going to mostly be your thing, get a bigger bike. Even just moving up to a 400cc bike would be an improvement.

Most assuredly. Anything over 65 MPH where I'm at, and the highway patrol or sheriff will be slamming on the brakes, making a quick three point turn and running you down for your autograph. We only have a handful of highway stretches with 70 MPH limits, and those are divided, multi-lane highways in rural areas, and interstates. Anything in metro areas drops down to 50 MPH or lower, no matter what type of road it is. I'm starting to see red light and speed cameras more and more, also. It seems to be a feature of smaller towns, with major highways running through them.

Our in-town highways are marked 65, and roll at 75 mostly. Out of town they are 75 with people mostly doing 80-85. Rural can vary from 55 to 75, with "everyone" doing 10 over. It's pretty well known that the state patrol has their RADAR set to alert for 11 over.

Have you guys seen this review?
 

I came across this review the other day. It's not a positive one...That being said, I think the guy did push it pretty hard. Although...the drag race between the Rx3 and the Prius is downright embarrassing!

Both vehicles have about the same power to weight ratio, and then the car has more absolute power and better aerodynamics, so, what should you expect...

Yes, I agree 100%

Everide wasn't a favorite here. Yes, he beat the snot out of it. Rode it like a MX bike, which it's not. Bottom line is, even after all the abuse, it didn't break.
