Slightly OT but David, how many miles do you put on a bike before you change them? You have about the same commute as me, and though I would love to do it on a bike, but 32k miles a year and the associated service/tyres/cost makes it rather unattractive!
Firstly, I don’t commute on the bike all year round. I "chicken out" in the winter months and use the train from November to March when there’s a risk of frost/ice. I’m too old to bounce and the bike is too expensive to fix! biggrin

Secondly, my bike is owned by my company so replacing it has less of a financial impact than it would if I owned it personally.

My last bike was sold after 3 years commuting with 54,000 miles on it. It had dropped in value (as judged by the trade in price offered) from around £15k to around £5k. As a company bike I, of course, got the VAT back on the purchase but the £5k sale price had to include VAT but that made the "financial hit" slightly less painful. Also, the loss of value is a company cost thus can be allocated against profits and thus corporation tax.

My previous bike is still currently providing sterling service to one of the other Old Gits (and occasional poster on here), and it (and he) was on this years Old Gits trip to Spain so the mileage doesn't seem to be a big issue.

Looking at all the costs, it’s a pretty close run thing between the bike or the train alternative but, taking everything into account, the bike does work out slightly cheaper. Surprisingly, it’s only slightly quicker but the convenience of not being tied to the train company's time table and knowing I’ll get a seat whatever, makes it a much better commuting option in my view.

Between ~110 (I ran out) and >200miles (I still had some left) out of the VFR750F but normally about 130

20l tank, so that's between 25mpg and 45mpg and mostly about 30mpg or so.

For some reason I get much better mpg when it's wet.... wink
Mine guzzled fuel around town but once on the freeway it barely sipped at the tank.

Lets see:

K1300S -- between 130miles and 260 miles on about 15 litres
Panigale -- between 80 miles and 150 miles on about 14 litres
VRod -- between 90 and 120 miles on about 15 litres
R1200R -- between 175 and 260 miles on about 15 litres

VFR800X Crossrunner
About 190-215 before the light comes on, which is between 50-55mpg with mixed use. I'm not often in the top 4k of the rev range though, what with avge speed cameras and spending a significant amount of time filtering.

Brutale 800RR does about 80 to light on a 16.6l tank.
The R6 it replaced did about the same.

I once saw 130 miles on a boring motorway journey but frankly I'd rather go the 'slow' way these days and use two tanks.

Thrash them and mpg goes down. Who'd have thunk it?

Thanks for this it makes a lot of sense!

BMW F800S

On daily commuting duties (15 miles each way split 30:70 Urban and A-road) i fill up every 200 miles and it takes 14.5 litres

On a long run (eg A303 up to London) I'll get 240 miles per tank at a steady three-points speed

So 60-70mpg as an average.

In the '50s/'60s/'70s it was possible to buy up to 50 litre (11 gallon) aftermarket tanks for BMW twins. Fuel consumption wouldn't be an issue with a tank that size.

I guess bikes were more comfortable in the old days. smile

wut? What kind of journey? Are you a lego jockey? A 125 4-T with less than 15bhp, and not enough weight to stop it blowing away in the wind, will only get to 100mpg if you make the effort to do so.
Not true. The PCX125, MSX125 gets a regular 150mpg on fuelly. The CBF125 about 130mpg.

KTM 390 Duke. Normal commuting use gives me 120-130 miles per tank. I usually fit in about 9 1/2 litres in when I fill it back up. Yes, it is an annoyingly small tank.

Seems to be better round town than on a run, but it's pretty good whatever I do - just as well really with that tank.

A lot of people fit smaller rear sprockets to these and fuel consumption is part of the reason - it's geared like a motocross bike as standard. First is near as dammit unusable, it's far too low even filtering through traffic.

High 70's appear to be the case with the CBR500R

http://www.fuelly.com/motorcycle/honda/cbr500r

90mpg is either an exaggeration or he isn't calculating properly.


I was wrong about the MSX and PCX.... they only get about 120/130 mpg.

It would just add more top end weight. Personally i'd rather keep filing up every 130 miles than have a heavy bike.

My MV Agusta Dragster 800RR triple ridden for fun only fast road would get 31-37mpg tank was 16.5 litres and I would fill when it hit reserve so about 4 litres remaining

My current Aprilia Tuono Factory 1100 v4 has a mpg on it and a 18.5 litre tank. Between refills Im getting 10 more miles before reserve light comes on. Mpg reads 29-34mpg

My track bike a Suzuki GSXR 750 will go through about 30-32 litres of fuel in one day which is normally approx 100 miles. That works out approx 14mpg

My MSX125 did about 130mpg - filled it for about £5 every 2 weeks.

My SV650S has just turned 120 miles and I'm still on the first tankful.

40ish MPG out of the R1 on the motorway. Half that if I'm battering it.

I've had 150 miles out of my ZX7R without needing reserve (never hit it)

I do 132 miles return at 100ish on the motorway with plenty of stop and go in London and revs and hard acceleration without reserve quite easily, tank then takes about 12-14L depending how hard it's been.
