tyre wear / paging Simian

what's typical rear/front tyre wear like on a ZX7R with D207RRs?

I'm guessing about 4000/6000?

Also, what's a typical service bill?

 

Sounds about right - get around 3000/5000 from the gixxer.

Depends what you mean by typical. If the shims aren't being checked,
it's basically oil, filter and slap a bit of grease around.

To check the shims (alternate services, according to the book, iirc),
the tank, fairing lowers, airbox and cam cover have to come off. To
*change* any shims, the cams have to come out. This is likely to be
2~3 hours labour, I'd have thought.

 

well, I'm looking for real world costs, i.e. what bills have people
actually seen.

Basically, I'm putting together a spreadsheet to compare commuting
costs of bike -v- public transport.

In case anyone's even remotely interested (and in fact, even if they're
not):

The bike's by no means looking like a bargain. I have two options for
public transport, either train to Liverpool St. and a 15 min walk, or a
train to Liverpool St. and a return tube to zone 1.

So far, I've assumed the 4000/6000 tyre life, about 200 quid for a
service (this is the average of what the 'blade's services have cost;
7R may well be less), 120 quid for a rear tyre, 90 for a front, and 50
quids' worth of fuel a month. (I would do about 550 miles a month by
bike, assuming 40mpg)

The results are:

Monthly Return to Zone.1 : 136.60
Monthly Return to Liverpool St. : 95.50
Bike running cost, including tyres, fuel and servicing, but excluding
insurance and tax, as it'd have that anyway: 102.25

Even halving the service cost (unlikely) still makes the bike cost 88
quid a month to use for commuting.

The conclusion is not that commuting by bike is expensive in general,
but it certainly is on a big-ish sportsbike.

 

Does that include the added depreceation of the extra mileage?

 

My commute (which is much much longer than yours) would work out at approx
2x the cost of the train ticket.
It just isn't worth doing in a car, let alone an expensive bike.

However, you *could* (but doubt you ever would) get a CG125. It'll be rather
different then I suspect

 

no, because the bike in question isn't likely to depreciate much
because of a high milage (it's a road-legal(ish) track bike). But
anyone commuting on a new sportsbike would need to factor that in -
probably quite a large amount.

 

well, that's what I'd concluded - to make it "cheap" compared to public
transport, it'd need to be something very easy on tyres, very high MPG,
and self-serviceable.

Additionally, on public transport, I get to catch up on reading, and
there isn't someone constantly trying to knock you off your bike.

The two costs are particularly comparable for me because either public
transport or bike takes approximately the same time.

 

This is hardly a shock, tho, is it.

 

no, but I wanted to do the sums so I could justify continuing to use
public transport now that the weather's nice.

 

My bug bear with public transport is it's unreliability. When it runs, it's
great.

When it doesn't, which is often, it's a pain in the arse.

That, and the public that use it.

That said, I haven't had a 3.5 hour journey home (normal 45 minutes) since
last year when a rat ate one of the main signalling cables

 

My journey seems to be "slightly delayed" reasonably ofter - say 2 or 3
times a month, but generally speaking it's on the way in to work, when
I'm not quite so bothered.

It's only been really bad a few times of the past couple of years.

Which compares reasonably favourably to have been knocked off twice in
12 months (both times due to pedestrians running out into the road).

 

You want one of these then

You do have to commune with mongs on public transport though

 

You're picking up spare wheels, fit a set with teflon tyres and double
the tyre life.

Do it yourself. Changing the oil and pads is hardly tricky, and that's
half the service done.

As if. 150 quid or so for a set from FWR, 180 quid fitted!

40mpg sounds reasonable.

How long will it take, how close is your house to the station, what's
the parking situation, and are you gay?

My car costs more to run than my 7R. Fear it. And 7Rs are so cheap,
if you **** it, buy another for under 2 grand

 

it's only a 30 min train journey, and living 1 stop from the end of the
line, I'm always guaranteed a choice of seats.

 

commuting to work is 40-45 minutes by public transport or bike. My
house is 150m from the station. Parking where? Do I look like Cane?

My car costs more to run than a 7R too - what's your point?

It's 1/2 Blaney's, and he's started hanging around with blokes with
shooters.
