With a 125cc single-cylinder four-stroke engine mated to a four-speed gearbox making 9BHP and overall curb weight of 225 pounds, how fast can the MSX125/Grom really go?

 

[chye]

I believe its 65mph or 100km/h.

Not going to be that stable at that speed though.

thanks, that seems like what the official top speed will be at and I have to agree at that speed on a bike like this it might not feel stable enough. At what speed range do you think it will start to feel unstable?

It doesn't sound like the Grom would be good for highway driving.

 

[chye]

Well I wouldn't recommend it. It's built more for the city.

Also depends on what freeway/highway lol. The highway I took today had an average speed of 30mph.

I think the Grom should be fine on the highway. Just stick to the right lanes and don't expect to be passing any cars. If you plan to commute the Grom during peak rush hours, traffic would keep cars from going high speeds anyways.

 

[chye]

It would be fine in rush hour but apart from that I'd stay off. You will cause traffic. Plus it won't be that stable at top speed either.

This!

I wouldn't recommend the Grom for highway use it's just too much to put this bike through, it's top speed is already at an average highway speed that would go with the flow of traffic.

I rather just keep the grom to city riding and short-distance highway riding if need be.

 

[Stars & Bars]

I don't believe Honda would put out a product that would be unstable at whatever top speed one of their vehicles is capable to travel at. 9 HP is leagal to drive on the freeways and mr chye, just as a comparison, Vespa makes a scooter, that tops out past 80mph and its got small scooter type tires.
Just saying.

Here in California, the minimum legal requirement to ride on a freeway is 150cc. Yes, you could probably get away with riding it during rush hour (since lane splitting is legal here), but there are so many idiot drivers in their cages in California, I wouldn't want to try.

Also, every vehicle I've ever owned (both cars and bikes) wasn't exactly "stable" at it's top speed. Handling is less than optimal at those speeds, since they weren't really designed to be driven that way.

Just wondering.

Does the 150cc requirement count if you put a bore kit on the Grom making the engine bigger? Or does it have to be a stock model?

Sad day

No, they will look at the model and give you a ticket. Sorry.

With a bike this small, top speed will depend a lot on the rider and road conditions, as well as how well the bike is kept up. If you don't lubricate the chain consistently you can likely expect to find a 10mph or greater drop in top speed.

 

[speedydave]

I'd say putting it on the highway would not be the best experience.

 

[Nitrod86GT]

For me you would be too low to ride in busy traffic. You won't be as noticeable. Basically it's like riding a go cart around in traffic. If I honestly was gonna ride in rush hour I would be an orange little desert flag off the back like they use out west lol.

 

[raylee]

Looking like a lot of dirt bike tech might transfer over with this motor. I'm hoping there will be a lot of gearing options as well as motor kits. Whatever the stock output is, I'm sure we'll be able to improve upon it.

 

[shleeve]

Yeah I wouldn't feel comfortable riding this bike on highway, but it could definitely putt around town much better than a scooter and have some get-up-and-go when needed.

 

[Dragontj]

With some suspension upgrades the stability will increase. Top speed isn't going to increase much I doubt

 

[Dragontj]

Well who knows someone did suggest a turbo and nitrous lol

It only has 9hp now that a bit of disappointment but I still like it cool look's there I beat it can't even hit 60mph if your luck from when I had my Honda 1972 CB100 with 11.5hp back in mid 80's that could easy hit 70mph flat out and before any high performance from powroll man she was a monster after add in a boat load of speed part she top out 110+mph pushing 21hp and speeding ticket to boot.

What (California, the minimum legal requirement to ride on a freeway is 150cc) when this happing when I live there back 80's freeway it was 185cc that minimum legal requirement then I never could take 99 I should know I live in madera I used to drive up/down 145 and 41 up to yosemite park or fresno or 145 to 180 in to fresno.
