Title: Increase Gearing for Touring and Motorway Use
Post by: Jbizzle on 21 June 2016, 09:51:28 am

Hi all,

Is it possible to increase the speed vs revs ratio of the gears for more comfortable use on the motorway?

I am going to be doing some touring over the summer, currently when at motorway speeds 70/80 mph equals about 6000/7000 revs.

I have always found the current gear ratios mean I need to change up through the gears really quickly when riding in town, especially getting out first. Basically I want to know if it is possible/economically viable to switch the gears out of my FZS 600 (2003).

Thanks!

Just change the front sprocket, as long as you have room on the adjusters. 1/2 a link forward per one tooth increase should be ok.

Ok thanks Megawatt,


Is it a fairly straight forward job?


Has anyone done this before and know the part/ part number I need? 


Thanks again.

Easy job if you have the correct tools. Remove sprocket cover, un do front sprocket nut first, undo rear spindle nut and adjusters, slide back wheel forward, remove old sprocket, fit new one, adjust rear spindle adjusters, tighten nut, tighten front sprocket nut, replace sprocket cover.

Add your bike, change the green custom front or rear teeth and check the revs  :thumbup

If you go for a one tooth increase on the front sprocket, and a two tooth decrease on the rear sprocket, your standard chain should fit perfectly and you will get a noticeable reduction in revs at motorway speeds.


And..... Better mpg on the motorway as well.

Here are all sprocket sizes for FZS 600: http://www.jtsprockets.com/catalogue/model/2681 (http://www.jtsprockets.com/catalogue/model/2681)

Front Available Sizes: 13, 14, 15 original , 16, 17, 18

Rear: 38, 39, 40, 41, 42, 43, 44, 46, 47, 48 original, 49

The problem with reducing the ratio is you loose acceleration. I have gone the other route reducing my front size. I do not do much touring though mainly town and commute.

Thanks for all the help guys.




Is it possible to swap just one gear? I.E just the 6th gear?


That way I could leave the rest of the gears as they are, and just get better performance from 6th?


Thanks,

Ive got 1 more on the front sprocket, far better on faster roads as the engine is waaay less buzzy.... But it can be a pain pulling off from the lights as the gears are longer and require more clutch slippage
