FXR vs GN

[FROSTY:Me]

What about the Volty and the GZ250.....they're all pretty much the same bike aren't they, but with different enough styles to change the riding position.

In my opinion no dude--all pretty much the same--

Hey Merv nah like u say will stick with my little GN unti licence allows bigger bike.

The FXR being a sports bike has more potential for speed as performance
engine/electrical bits are available here in NZ.
For commuting the GN is fine as town use requires low fuel use and reliablility
which they have.

Note this though:

Both bikes are not quality Japanese made with this exception:
Early GN's (1980's) are made in Japan and are superior in every way
to asian stuff eg thailand, china, mayasia.
The market is flooded with non-japanese bikes which are mostly poor quality
including the suzuki stuff RG150 FXR150 GN250 SJ50.
When I worked in the trade I seen these bikes for what they are - avoid like the plague.

Heres a Good example and I have many more:

I have friend who owns a Suzuki AX100 (original 1983 model) and who brought a brand new (chinese I think) AX100 a couple of years ago.
He told me recently that the new one has degraded so badly and quickly that his old one has a better all round finish, (chrome, paint etc) now than the new one with 20 years difference!

There is not much to choose from these days I know.

Ahem, FXRs use are a lot more fuel efficient

I am a bit new at working with image programs,but this gives some idea of what a GN could look like.

... but would you waste money changing bikes like that to an FXR when in my view you'd be better to save your money and putting it towards something at a different level altogether like a full noise 250 or something bigger when the licence allows?

What do you mean by a "full noise 250"?

[merv]

Something like a CBR, ZXR or Bandit that's putting out more like 40 hp, not the lower power singles like the GN.

As with the other suggestions about bars etc. I'd personnally go down a size at least for the back tyre and replace the chain/sprockets with decent aftermarket jobs at 6/7,000kms as that is all the OEM items will last judging from the gents at works one he bought new.

nice but still gn250's are too slow

The FXR has about 20hp, but the RG150 has 36hp. Which is nearly 40hp, does this make this 150cc bike a "full noise 250"?!

Nah it makes it a full noise 2 stroke 150. Its the state of tune being referred to of course. You just got to keep up with the language or give us some of your own.

"State of tune"?

"State of tune"?

Are you a real nOOb or are you having me on?

State of tune is the level to which the design team has pushed the envelope in tuning the engine to extract the kind of power they want. A low end machine may have mild cams (4 strokes), maybe lower compression, maybe smaller intake and exhaust valves (and maybe even less of them e.g 2 not 4 or 5) and ports and header pipes, perhaps a longer stroke to bore ratio in the cylinder and basically be designed for a slower revving life with not so much top end power and rev ceiling as a "full noise" engine which will be tuned to extract as much power as possible from the engine size - except when we are talking road bikes we are still talking tuned for at least some longevity for road use. Racing engines are tuned to higher state of power output with more attention to all these things plus these days electronics are playing a big part in controlling ignition and fuel injection to optimise the fuel/air mix and ignition timing and burning of the charge in the cylinder with optimum flame paths from spark plug etc. Do you get that now because otherwise I could go on and on and I am sure someone like Motu could add a lot to this.

The state of tune explains why my XR250L is 28hp at the crank whereas my WR250F is about 40hp for the same engine displacement. They are built to a different state of tune for different purposes. One will rev to about 9,000rpm the other to 13,500rpm.

A real n00b? Well, kind of. Often I can guess at what is meant by stuff said here, but still.... I can not be 100% sure. So often I'll ask questions even when I think I know the answer, because I possibly I don't really know after all.

Thanks for the reply, that is roughly what I thought. (those wasn't thinking in quite that detail!)

Though still don't see why the GN250 is underpowered, I presume the design team was simply going for outright cheap. Or perhaps fuel economy. What is the design intention with a cruiser engine?

No worries, no harm in asking.

With the GN I am sure the design team were putting together something kind of soft and easy to ride around crowded Asian places with longevity and fuel economy in mind, not outright power. The fact it has a sort of high bar cruiser look about it I am sure was purely for some idea of a style wanted by its potential buyers.

As for the bigger cruisers it all seems to be about this how much torque can you get at low revs so the riders can cruise along in high gear just taking it easy with the rythm and vibration of the engine giving them their jollies or something like that.
