View Full Version : Honda CBR125 review - Nicer than an fxr but needs slightly MORE POWER!



motorbyclist
1st September 2008, 23:16
So today while I waited for a chain/sprocket to be fitted on my little brother's 250 hornet, the kind fellows at Botany Honda let me take their CBR125 out for a spin despite me telling them I had no intention of buying it, but did want to have a blat due to the volume of new riders in the uni club asking about good learner bikes, so here's my review:

She's a 125cc fuel injected single, watercooled with 6 speed gearbox all up weighing about 130KG. Fully faired, single discs front and rear, standard suspension.

Basically it's a new FXR150 with smaller bore, injectors and another 10 kilo's. Having ridden the FXR quite a bit in the past and present, I'll largely compare the CBR150 to the FXR150. Honestly, arguing/comparing these to a 250 is just silly. For the record i'm a pretty skinny guy, about 60kg, around 6ft tall, riding since I was 12.


Initial impressions: farking light and nimble, not too bad for $5k even though they had a VTR250 going for the same price, comfortable, low power; perfect for a learner but no good for open road.

Set off out the door and onto the road. Damn light bike. Narrow seat but nowhere near as painful as the FXR seat. Brakes work well, 35km old stock tyres have plenty of grip. Horn sufficient to wake up driver who hasn't seen the lights change. The engine is smooth, dead quiet and the engine brake isn't anywhere near as ball-crushing as the FXR. Of course the first thing I do is weave around like a drunk and DAMN this is a light bike; it may weigh slightly more than an fxr but it's noticeably more nimble.

Went down the road initially to get some lunch, but soon ran into some mates. As at that stage I was officially "between bikes", I told them it was my new one;). Either way they all thought it was a pretty cool looking number in black, and we found it "interesting" that one light did low beam, one did high, and only one was working at any given moment. I never found a pass light button, but never needed to look for it....

We then decided to go for a quick ride around Point View Drive and back around via suburbs to botany. Starting with the steep hill climb I lost speed pretty quickly to the point where I dropped well below 50kph before nearing the top. Once making the crest came the speed test and, well, despite the dealer telling me it's get some power above 9 grand, it redlines a bit past 11 without doing anything too stunning. Thanks to the fuel injection I didn't really notice a band, just a gradual increase in power.

Long story short; I never exceeded 92kph, even down a hill. There simply wasn't enough clear road to safely do it. While I'm sure this could do motorway speeds, it will take some time to get there and you'll be in trouble if it's an uphill onramp. Definitely less power than an FXR150.

At speed the cornering was fine, very responsive etc etc and ride was surprisingly smooth for such a light bike on a rough surface.

Had one hell of a fright to come around a right hand bend to meet a black car bang in the middle of the road and immediately behind it a silver one peeling off into a driveway (indicating, but obviously didn't even bother to look before entering oncoming traffic), effectively blocking the whole fucking road. Many words uttered into my helmet, brief consideration to turn around and ask exactly what the fuck they thought they were doing, but I digress.

Now back into the suburbs and this bike went back to what it was built to do. Being so narrow it could split through the narrowest of gaps, the mirrors were good and didn't just give views of my elbows, and at the lights it still had enough juice to get clear of cars, but I did have one worry when changing up into 6th it hit neutral while cruising through a nice left hander at approx 50kph....

Took her back to the dealer, thanked him and told him about the gear missing. Considering I'd just upped the bike from 35km to only 45(ish)km, perhaps there's a problem in there somewhere from a previous test pilot, or a genuine fault, or poor design as I while was pretty light on the stick it shouldn't be able to get lost like that. At least there wasn't a crunch when I got her into 6th.

Conclusion:

This is a very capable learner bike. More comfortable than an fxr, good "neutral" seating position, light, nimble, smooth power, no sharp edges and even has a fuel guage. It would make an excellent commuter, basically just a nicer, if a bit underpowered, version of the FXR150. But, of course, like the fxr this wouldn't be any good for high speed riding. I have taken the fxr150 on a few rides and it can do it, but the CBR150 just seems to have too little power in too short a rev range.

So if you've got $5k to spend on your first bike and want something reliable to pootle around on to get to school, the fuel injected CBR125 is a good way to go. If you want to hit the motorway, it will do it but isn't going to be great, and the FXR will do better but is much worse for comfort and mirrors. If you weigh more than 80kg you should be looking elsewhere.

Will I recommend it? Yes, to those who it would suit, who may as well go and buy a scooter but good on them for getting something with handling and brakes.
Otherwise I still firmly believe (in most cases) the VTR250 to be the best learner bike out there, followed by the classics like the GPX250 and then the heavyweight GSX250.



Learner bikes I'd still like to ride:

honda jade
hyosung 250 - been up/down a driveway and wasn't impressed

Sweet review man.
Yeah, I'm thinking the 125's are more of a scooter replacement than anything. :P

Rumour has it that yamaha may be making a 250 version of the yzfr125, that would be an interesting addition to the 250 market.

It's odd, isn't it, that the FXR150 made around 20hp with 12,500rpm using an old-tech air-cooled engine. Brand-spanking new CBR125R comes out with watercooling and fuel injection and all the shiny bits and makes 13hp with 11,000rpm. I wonder why? Is it because of the target market (Indonesia, Malaysia etc.), they want to make it low-stressed and reliable? Cheap on fuel?

On the other hand it was the UK's #1 selling bike in 2005, and apparently they still sell them by the shipload; the UK being a place (apparently) where they frequently ring the living shit out of learner bikes just to keep up on the 90mph motorways.

There's a CBR150R too, supposedly made in the same factory in Thailand alongside the CBR125R. It makes around 19hp apparently, FXR150 territory.

don't, looks can be decieving
70mph top speed
4 stroke......

im sure briggs and stratton made more power
Makes you just want to weld a Victa 2 stroke into a GN

the power restrictions are too meet licencing laws over in europe and japan

the fuel injection is to meet the emmissions laws in europe and japan, and give a bit more power . i would add the states but they won't buy anthing under 600cc:p

same story with the NC30 being restriced to 59HP and then the NC35 being restricted to 53HP to meet changing laws, these 125cc bikes are to meet the current licence restrictions.

FXR is DOHC, CBR125 is SOHC
CBR150 is DOHC, makes 20hp

I fail to see what that has to do with it? DOHC might give you more RPM due to not using rockers, but the difference in redlines between them is only 1000rpm, so that's moot. You can get any cam opening profiles and combustion chamber design you like with SOHC and rockers that you can get with DOHC.

Not an explanation, but comparing apples with apples.

You want fxr power, buy the cbr150.

Also, could it be a marketing ploy? leaving space for a (future) cbr125r with 20hp perhaps

The latest model RS125 bike comes out with around 15hp at the wheel, it can be derestricted to 30hp+ and still 'reliable' apparently...

I'd call it emissions regulations more than anything else.

Ah yup yup. It would have to the CBR125RR -- this is actually already the CBR125R -- Honda like their Rs! :sweatdrop

If you think a road going standard FXR is 20 hp guess again. Even a ported, hot cam, race CDI, Pipe and Flatslide carbed fxr would struggle to tip 20hp. they're more like 15hp, and the FXR is oil cooled.

Iwas in Aussie last year and they were punting CBR125's out for $3995.

You can get any cam opening profiles and combustion chamber design you like with SOHC and rockers that you can get with DOHC.

what are you failing to see?
Engines make more power when DOHC. When was the last time you saw anything modern, performance orientated and SOHC?

The CRF150R is a sigle cam and I'm pretty sure the CRF 250s are as well. They pump out plently of power for the capacity.

Plenty of modern performance orientated SOHC engines. Above post lists but a few.

Care to explain why simply changing the head design to DOHC adds moar power?

The answer is it doesn't. The advantage of DOHC is simply less reciprocating mass, by eliminating the rockers. This lets it rev more with less stress on the valve train; however, as mentioned, it's irrelevant as the redlines on these two bikes are very close.

There's a few more advantages of DOHC, but not really to do with performance. No. 1 is less bits to wear out and go wrong -- rocker arms (and the pins they rotate on) wear out and mean more frequent tappet adjustments. Packaging is also a little better, I was reading an article about the 70s Kawasaki multis, how using DOHC meant they could have the combustion chamber design they wanted without making the engine too tall.

DOHC slapped on the side of your engine is about as useful as determining performance as a big red R decal on the tank of a GN250.

lol i remember back when i was 15, showing off my shiny new FXR150

one of my mates saw the "DOHC" on it and went, "dohc? on a 150?! what's the point?"

Thanks for the review, which is perfect for me.
I'm on my learners, and I'm actually weighing up whether to get either a brand new CBR125R for $4500 from Counties Honda, or a 2002 FXR150 from Trademe for under $2000.
I'm pretty much decided on the FXR.
The slightly greater power will be good.

according to suzuki the fxr puts out 20hp

and the only cbr figure we have comes from honda

so either dyno the two machines or use the numbers as a guide

or just believe me when i say the fxr has more grunt

26th November 2008, 14:32
And these people that think it needs a DOHC to rev harder, just look at Honda using SOHC Unicam on their CRF250R motocross bike. Everyone else (I think) uses DOHC but the Honda ain't disadvantaged.
It's got the same 32KW as the KXF, RMZ and YZF.
(yes, I know they're race motors though)

My GN140 revved to 12500 for two seasons before it let go :lol:

They've had a worked FXR and a CBR on a dyno down here I don't think either of them were over 20 RWHP and the CBR is the faster bike

(especially with 60kg midgets on them)

I think they mean 20hp at the flywheel, not at the rear wheel.
So it would certainly be less than that on a dyno, and that even with a properly tuned engine.

So I bought the FXR150 yesterday. Good to be back on a motorcycle again - it's been years since I last rode - and my first ride on the new bike was Hamilton to Auckland, and on a learner licence, so sticking to 70kph!
Sheesh, that is dangerous on the open road!
It's more dangerous driving at 70 with trucks roaring past than to go with the flow of the traffic. But I digress...
As the original review said, the fxr seems to have enough power to cruise comfortably, but after an hour and a half of riding, the seat was starting to be VERY uncomfortable. I don't know how that young fella did his North Island tour on one!

It's well worth taking the seat to an upholsterer and getting another layer of foam inserted under the skin. The extra 10-15mm makes a big difference. And it's a cheap upgrade.

Cheers Danboy, That's a pretty good idea. I just rode to Thames and back today (just got back half an hour ago) and same problem, sore butt!

So I might get Stu's Trim Shop to quote me up. I know they do good work.

I reakon the cbr's are a weapon, ive done 130km/h out of mine with just the road gear stripped off it and some good corner exit speed. Given alot of FXR's a good eat my dust at the racetrack.

They are nicer bikes than the fxr's, more comfortable and have better handling as they are more modern, Fxr's arnt as quick as a cbr to 100km/h.....but fxr's have abit more grunt after 100km/h....
