Shaft drive vs Chain drive - benefits or drawbacks?

a big part.

A totally fucked chain/sprocket is less efficient than a shaft. A new
chain is much more efficient.

On an FJ the shaft has to go through two right angles before it drives
the wheel. This makes it almost impossible to sit on 60 km/h.

Methinks, if that was right, you'd see a shaft on a RC211V.

 

XJs seem to suffer the same problem Theo.

It's pretty much in that category ... it's just as easy to change
as check, and while I'm waiting for the oil tank to drain ...

And yeah, it often seems to have picked up a bit of water ...
the breather isn't really well designed for river crossings.

You wanna buy a z13 then!

Yeah, the GPz1100 is far superior.

Mate of mine had an FJ.

 

Anyone care to run down the benefits/drawbacks of shaft drive versus

no benefits to a chain that i can see
you have to;
lube it...at lunch stops on long runs
adjust it...once a week? or at dinner stops on long runs
clean it...once a month
replace it AND the sprockets...after 25000 k...so that's another $300 a year

whearas a shaft needs spline lube and a change of 'diff' oil...oh...say once
a year

nice...solid...classy...top touring weapon...do not attempt to corner faster
than 160 k...fit extra spacers to front springs and 15/20 wt oil
oh so smooth motor, will do 200 kph loaded, unloaded, solo, two up...will
not go any faster
can be a bit top heavy, not a problem if you are 6'
if you are 6' your knees might bang on the fairing
has a wierd side stand, easily fixed to be non auto-retractible by moving
spring mount point

Kawazake GPZ900 {chain drive}.
dunno, never had one, wanted an 18" front wheel model, have been warned off
16" models by people who owned them
but it has a chain...ewwww

nope, ignore all the stuff about wheelies and the 'dreaded torque steer',
its crap

probably
if i was racing for rego papers i'd take the GPZ
if i was going from one end to the other, the BMW

braking is prolly quite similar...likewise power
i think a sorted GPZ should outhandle a K100...however not many ran away
from me when i had a K100RS, and they will go hard in the twisties, until
you get to the open stuff where the 160 k limit applies...it will tie itself
in knots if you go faster, and objects to being pushed hard on wavy surfaces
a sports bike from '88 on will leave it for dead
<dependant on road conditions and rider skill, but about 170 is IT>

in terms of economical vehicles with sporting pretentions i agree with Clem
an XJ900 is hard to go past...a 650 is good too (had one of them)
K100RT is a VERY close second...might be easier to find in good nick, offers
better weather protection and BMW is a classy name that goes down well in
all circles

 

Heh, same here. Popped the clutch while sitting on about 5k5 rpm at the
traffic lights. It was a pretty odd feeling. Three months later, my
gearbox blows up.

The needle bearings in my drive shaft had pretty much seized at 100k km.
Found a secondhand replacement and it's going well.

One thing that I notice is that there is hardly any give in the drive
train. Whatever happens at the gearbox/throttle goes straight thru to the
back wheel. Accelerating hard feels a bit odd as the back of the bike
seems to lift rather than drop (my model is pre-paralever, don't know if
that has much to do with it).

Depends. The Monolever K's shafts do need care: pull the rear drive,
clean and grease the splines every year or 20.000km. Takes about an
hour, hour and a half.

I haven't heard of Paralever K's (the 16V engine ones) busting their
shaft like the aircooled GSes tend to do, but that doesn't mean they
don't. Keeping the rear splines well greased tends to help, and you
can have the shaft's U-joints fitted with a grease nipple (aftermarket
job, dunno if there's anyone doing that down over at yours).

The ones that run in oil, like all of the pre-'86 R bikes, are pretty
much indestructible.

Why do you say that, Cam?

I'll give you a bit more info - I'm 197cm tall, and weigh in at over 150
kilo.

I don't think a 250, or even a 600 will cut it hauling this fat arse
around.

I'm aiming at something bigger than about 900cc because I've seen what
can happen when you don;t have the power to get yourself out of trouble
- and me on a 250 or 600 would definitely classify!

Fair enough.

Thank you. A concise, and easily understandable explaination for someone who
doesn't have a clue.

The BMW is looking more and more attractive all the time.
