Steering head question.

If two bikes share the same external diameter for their head bearings,
would this suggest that the two front ends are interchangeable?

Just thinking out loud about a solution to the CBX front end's
shortcomings.

You'd need to look at the length of the steering stem tube and depth of
the bearing races to get a better idea, but if they are identical then
there shouldn't be a problem. Internal diameter isn't an issue if the
same bike's stem and yokes are used together.

 

One suggestion from elsewhere is to press out the stem from the lower
yoke, and press it into the new one.

Those 35mm forks are simply not up to the job. The CBX is around the
same size as the CB13, and that has 43mm items.

Allegedly, a pre-2000 B12 front end might do the business.

Of course, if that works, then the tail-end will become the weak
point.

 

I've seen this done quite a bit on RDs and LCs, and also some of the SV
boys fit USD front ends from all manner of bikes because the stock
forks are shite. Its not a difficult job and doesn't need a genius to
complete the work, but they have to make sure it's all lined up
correctly

 

Not necessarily. The steering stems themselves might be different
lengths.

your sig is getting more like geekcode every month.

Aye, I fitted RGV front suspension to RD without any problems, apart
from a spacer which is readily available from the RD forum it went
straight on. Harder work getting clocks etc to fit/work.

 

It just growed like Topsy ...

 

to paraphrase ukrm circa 1997: The cheapest way to make your bike
better/faster is to sell it and buy a better/faster bike.

 

Perhaps a METAR or a TAF?

 

*ding*

"If you want a faster bike, go and buy a faster bike". Right?

 

Five to one the problem can be traced to the 'outrigger' castors which
are screwed into the lower extremities of that unfeasibly wide engine.
When they touch down, obviously the bike wobbles a bit and tries to sit
up.

Can be alleviated by removing the castors and fitting sparky slidery
bits instead. Or refitting the engine in line, of course, pivoting
around the central bolt and spinning the output sprocket to suit. This
then feeds the existing drive chain thriough a primary chain via a
thrunging sprocket, thus converting it to a proper gentleman's
motorcycle.

 

Arse. Outpaced by 90 seconds.

I need a faster newsreader.

 

"the cheapest way to make your newsreader faster..." etc.

 

Yeah. Thank you, Mister O'Murray.

 

One with brakes would be a bonus.

Oh, but I do, but I could enjoy it *more* if it stopped quicker than
an oil tanker.

This idea was to enable a switch back to stock to be as simple as
possible.

Ah.

 

Adaptors with some modern calipers (and possibly disks) would be the easy
option, look fairly kosher and easy to put back. And a decent master
cylinder perhaps. Comstar wheels IIRC and anything else would look odd.

Have thought a bit of attention to springs and oil would make the suspension
at least tolerable.

The OE Bandit front end doesn't exactly have wonderful brakes.

Are the tubes 35mm? nothing much better came in that diameter. GS and CB
750's were about the same. An early FZ-600 would be about 36mm however and
I've fitted 1mm over forks into yokes.

 

You talk out of your arse.

They are good enough to hoist stoppies from 100mph, how much better do
you need for the road?

 

Do you think SD was talking about a new 1250 front end? or maybe a 1996
1200 system.

 

See Loz's response.

Whilst the brakes on my Bandit won't squeeze your eyeballs against your
visor, one finger at 120 is enough to make the tyre whimper. The
grudging, grumpy MoT tester last month said they were impressive and
the guy before that noted that they registered the highest readings
he'd yet seen on his rollers. More than adequate and I daresay a sight
better than the OEM CBX brakes, from my experiences with Hondas of that
generation.
