The opposite of downgearing.

Upgearing if you will....

Has anyone done it before? I'm about to replace my C&S on my k2 sv and since I'm off to france in a week and a half, I want to save as much mpg as possible. I am not expecting to hoon around, just do a sight seeing holiday really so I don't care about the power.

Just wondering if anyone has done it before and to what extent? -1, 02 on the back? Any noticeable mpg benefits?

Dizzyblonde has, she complains a lot about it, but I've ridden it and it's fine

She was using far less fuel than me on the way to the AR, but I had a pillion, all the luggage in the world and the aerodynamics of a brick, pushed forth by a not particularly well carburettored engine. So it means fk all!

My black SV is higher geared. Its superb for mile munching. Think its one up on the rear sprocket. As for petrol, it seems to run on fumes the further you get on a motorway! I bought it like that, and as i was going to France on it, it was perfect for the long mileage.
Anyone that travelled up to Scotland with me would back me up that it just cruises along at speed at ease. Just a little odd on corners, theres less rev for more speed if ya get me. I have a standard set up on the yellow SV and there is a significant difference



edit... YC I only complain about it as its not suited for corners like the standard set up is. I have to work the gear box significantly more on bends etc compared to the other.
But I get cheap miles per gallon!

How does that affect the top speed dizzy

I was just thinking about doing this mod this morning.
What kind of mpg do you get with -1 on the rear sprocket.

In 6th gear I can go and go and go and go. She pulls like a train. On a motorway that is. It feels very comfortable. I wouldn't know about top speed as I don't rag the pants off me bike. Erm, i got up to 110 at the weekend round the rideout, and she wanted more, I'd say about 6-7 thousand revs?. Its the highest I have ever got her, but If there was someone with more confidence riding, then I'm sure it would get a whole lot higher with ease

Thanks Dizzy - Sounds like it's a winner to me then.

I plan to do about 2500 miles or more so any money I can save the better. To be honest, any saving I make will probably be lost by the use of a topbox, panniers and a standard screen! But any saving I can make is a bonus.

Whats the standard gearing off the top of your head?

depends if its a nakid or faired on the gearing thing.
As for getting speed etc, if its owt to go by, at the weekend I was carrying full tankbag of spares and oil. tailpack packed to the rafters. on the rack I had sleeping bag and pillows.

edit: standard sprocket 15 teeth front.....45 on rear(nakid)....44 teeth(faired) HTH

Thank you very much!

I have a faired machine myself. I'll go for 43 on the back, purrfect! Would hope it wouldn't affect the length of the chain being purchased!

Wait a second, doesnt it increase top speed, increase cruise speed by lowering rpm, and so reduce mpg if you reduce the tooth count on the rear, as apposed to increasing it?

The only way im working it out is by comparing it to riding a mounting bike - smaller cog, low rpm at speed - lower mpg.

Bear in mind, im a total noob so im probably wrong.
