AMERICANS: Would you buy a 125cc motorcycle for the street?

[ProDigit]

Yes, Curb weight is 348. That's the weight topped off with fluids.

But my bad, because I swapped out the exhaust for a Danmoto one, and got almost 14LBS off the weight (the stock exhaust is heavy) to 335LBS.

350LBS is about as heavy a bike as I would want.

I have been trying to find a way to import an Aprilia rs125 as a street legal miniGP race bike. They kick around used all over europe as discarded beginner bikes.

Megacool!! Heavier than I'd like it to be but on the other hand it's got all the "good stuff" like a modern liquid cooled EFI engine and an up-to-date chassis.

A top speed in the mid-70's says a lot about how well this puppy runs, too.

It ALMOST makes me wish we had tiered licensing here so there'd be a market for 'em. With the 300 sport bikes around 50 lbs. heavier and likely cheaper to boot (I didn't get a price on the Aprilia) until beginners are mandated to spend time on 125's--or there's a huge change in the bigger-is-better mindset here in the U. S.--I'm afraid this will be an exotic we'll only see in the hands of those willing to jump through the hoops to bring one in.

That's sad because this one is really, really neat!!!

Can you put aftermarket tunes for performance or mileage on the efi bikes? Does it adjust for altitude automatically? No more tune up beyond filters and oil? How is the reliability?

Please succeed.

12.5:1 compression ratio and a quickshifter? Um, yes please! I plugged in the gearing numbers and it is stupid short gearing, 45 mph is 7188 RPM.

In USA, they will be good enoigh for the city or the go kart track, and even then, they probably will be outperformed by a kawasaki Z125 pro, or a grom 125, both are lighter in weight, and more comfortable to ride.

I have the CBR300r, it works great everywhere, save for the interstate.
What we really need is a 400 cc bike like this.

There are a lot of people out there who look at pretty colors, but not the functionality, and this bike aside from looks, is just not functional in USA.

If I were to buy a 125cc for the city, it would either be a cvt belt driven scooter with storage space (cargo), or a tiny, lightweight,comfortable upright bike.
If I want an all rounder, it would be a lightweight 350-400lbs, 400-600 cc naked bike, or a 450-650cc cruiser bike.

I think the sport bike category should start from 600cc and up. I personally think there's no reason to go higher than 750cc on a sport bike, but who am I to say, when lots of hayabusa 1200cc bikes are sold?
A 750cc sports bike starts being fun at 100+ mph, but I guess that doesn't matter to some..

Anyway, I just don't think there's a big market in usa for small bikes, let alone small sports bikes. Look at the Sym Wolf 150. An awesome bike for the city, but almost zero sales.
People here prefer to trade on some mpg for the slightly higher performing 250cc models, and now are 300cc models, until the manufacturers bump it to the 400cc sweet spot.

That is unfortunate,
These bikes can pull 4k rpm at 40mph, and even 3k rpm at 40mph for fuel efficiency.

Outperformed in which way? Honda UK website says the grom has 9.7 HP while the CBR 125R has 13.1. The grom/Z125 are certainly not outperforming the CBR 125R in my desireability index.

How many cylinders would you prefer for that all rounder? Honda still makes the 4 cylinder CB400SF equipped with fuel injection and VTEC yo!(only sold in japan............................................)

Its a little heavy for your tastes at around 430 pounds curb weight. That is another bike I am going to be waiting 14 years for. Kawasaki recently introduced their ninja 400 here, which is only two cylinders and is only a sport bike for now. Hopefully the other manufacturers will follow their lead. I'm hoping they make some 3 cylinder 400s, right now the smallest 3 cylinders bikes I know of are triumph's 675s. Yamaha is actually making a 400cc standard bike that is 384 pounds, the SR400. Its a single cylinder air cooled, and is kick start only, but it seems you like simplicity anyway(or was that woodsrat?). Plus kick start = cool points.

HISSSSSS. I think even 600cc bikes are too powerful to have fun with on public roads(without fear of getting arrested), specifically why I want a 125. I want to be able to pull away from a stoplight full throttle and shift at the rev limiter without making cops think "That guy is racing! Lets give him an aggresive driving ticket and throw him in jail!". The new CBR 250R is capable of around 8 second 0-60s which is a little fast to do right in front of a cop.

Yep, and now we wait.

• Yes, aftermarket tunes are available but they are not legal for use on the street.
• Yes, EFI automatically adjusts for altitude (and temperature)
• You still have to doing the same scheduled maintenance.
• I've never had to touch the intake system on any of my EFI bikes. Push the button and they start even after sitting for months. I've had to fiddle with the carbs on EVERY carbureted bike I've owned.
