Riding a 250cc on the freeway?

Sorry? Can you explain this one to me?

Ummmm

Fuggin' what?

You forgotten your DT175 roots alreay?

I hate to think how many hours I had that thing (DT175) wound fully open
(after altering the gearing to get decent highway speed and fuel economy).

Don¹t make me start, as I will be telling my touring stories to Kathy for
weeks!

Go and do some basic physics .. you're a fucken idiot.

The longest trip I've done on a 250 was Canberra - Puckapunyal on the GPX250 (about 650km). Except for a short stretch
on the Barton Highway at the beginning, the whole trip was on the Hume Highway at or exceeding the 110km/h limit. At no
point did I have any trouble holding that speed, nor with finding a bit extra when the need to overtake arose.
Admittedly, the GPX250 has a bit more go than a CB250, but I think it will do just fine for a 40km trip! And if you
still have any doubts, ask BTH about his regular epic journeys on a GPX250 (Canberra - Ayers Rock on one occasion, and a
complete circuit of Australia on another).

I did 30 Km a day on a CBR 250 RR for 1 year. I'm glad I got that bike as
it had enough power to overtake with ease, cruised at 110 and was fun to
ride on weekend rides.

Actually rode the bike from Melbourne to the OX and then to the Queensland
border and back, bike didn't have a problem I personally wouldn't get
anything that struggles at 110, sometime you want to go for a cruise and
not having to hold your bike flat makes it more enjoyable. Also to avoid an
accident its good to have another option than breaks.

 

I used to ride a Kawasaki GPZ250 to work every day, but it was only
about 10 minutes on the freeway, no problems.

The CB250 will do it without any problems, but if I was going to do this
commute long term, it's not the bike I would select.

Being a light 'naked' bike you are exposed to the wind and weather to
much. After a while it gets annoying being buffeted around and you'll
ponder how much better it would be, to have more weight, and maybe more
protection.

I would suggest a 600 cc bike with a fairing for this commute, if you
plan to keep this job long term, because after a while commuting this
distance on a 250 will become a chore and you'll probably regret it.

Go and do some basic physics, it's moving along a road
against the wind, tyre rolling resistance, incline, and
Einstein-only-knows what else, not falling from the sky
in a year-12-physics perfect (wind resistance-less) world.

Oh, and you can't spell "fucking".

I think it is more, go and check the real world instead of physics
theory. I think I know where you are coming from, but real world says
"no" to that.

Nice try Sharks but if it's at the top end of it's rev range to sit at 100 *in
top* then downshifting at the bottom of the hill isn't going to be pretty (not
even CBs will put up with a lot of that . And while the gearing is unaffected
by the rider's weight, the maximum speed the vehicle will pull against a certain
gearing ratio is impacted by the riders weight (ie if you're a fat **** it aint
going to keep that 100K happening as soon as even the slightest rise appears on
the horizon - whereas if you're Cat, the bike won't even know you're there)

Blimey, what is this ? Pick on JL night ?

I was referring to the twins in the list of alternates as opposed to the fours
in the list of alternates ! Sheesh

JL

 

ROTFLMAO !!!

You've obviously never ridden a low HP bike then.

JL
Hint: there's a correlation between the highest gearing you can pull, mass being
shifted and HP/torque

 

If you are going to get a CB250 for freeway use , then get bigger carby jets
for it.
Replace the #35 slow jet with a #38 and replace #110 main jet with a #115.
The jets cost $28 for the two and 1 hours labour at a bike shop.

I had my CB jets replaced with the bigger jets and I have found that the
bike runs a lot better at speeds faster than 60 kph and especially on the
freeway @ 80 kph - 100 kph.

The fuel usage is only about 2 - 5 Km / litre less than with the stock
standard jets.
Before I was getting 28 - 32 Km /litre using the stock jets and with the
bigger jets I am getting 25 - 28 Km/litre , with a lot of freeway use , you
will probably get 28km /litre.

I'm trying very hard to !! In fact I'd suggest the CB over the DT any day !

Yup the poor thing I had spent a lot of time with the throttle wide open, dog
only knows how it survived it.

Tell 'em to VB - she hasn't heard them before....

CB250? hell i guess it'd do the job quite well, but as Zeb says, you certainly will *not* be
the fastest thing on the road.

Also at highway speeds you'd be up in the rev range and im not sure if it's just me or not,
but even while taking a blatt around on a CB250 on my P's test I found the power to be
in the middle of the revs, and it quickly turned into vibration at anything about 6k RPM
(im gathering that'd be about 90ish km/h in top gear).

At the end of the course i was *very* glad to go home to my EL250 which felt a HELL
of a lot smoother (vibration and power deliver wise) and balanced (ok ok so it had a
few more HP too which came in up to a 14k or so redline).

But if you like the feel of it, and dont have any niggling feelings about its handling, by
all means get one. But in all honestly the GPX's, VTR's and Spada's these guys on this
NG are selling would *certainly* be able to do what you want (and possibly have a little
something in reserve "in case" you ever needed to get around that semi going up a hill.

I ride a Spada (Honda VT250) and have been for about 5 years with no
problems at all. Top speed I get out of it is about 160. I have toured
around Tassie and doing it again soon, as well as treks down the Hume to
Sydney and the GOR to SA.
Its a great little bike that is very under appreciated. Cheap to fix, run
and easy to work on.

 

Precisely, why else do you think lams is based on a "power to weight ratio" bugger ?
Also why the hell else would a R65 Bimmer be on the list? got a shedload of power,
but as heavy as a sherman tank. And by that logic a WRX blinged up to the
max should whoop the butts off anyone with a 'busa if we followed your logic.

Sure wind resistance has an effect on things, but the real issue is something to do
with propelling force, inertia, momentum & weight.

Mike.S

 

Forget the CB 250 and get a Honda Spada VT250, much better bike for riding
on the freeway!

Its got a great 90deg V-Twin engine and a six speed gear box.

 

Ha ha ha ha ha.

You are sooo funny.

Your weight changes the gearing?
