I have a 2015 SX of which is a bit revvy in top gear (4500rpm and 48mph)  can anyone suggest a gearing set up that will increase this to a more comfortable 55mph with a few less revs

For a 2015 machine I suggest a 16T front sprocket  :028:

I found my 2014 a bit "revvy" too and wanted to decrease the revs at any given speed for long distance work. This would also improve the economy.

I now have a 16 tooth front (+1 on std) and a 40 tooth rear (-1 on std) This combination doesn't affect the number of links in the chain and doesn't affect the traction control or anything, ( I do think that post 2016 models need some re-mapping here )

At stock the bike did 81/82mph at 5500 revs in top, It now maintains this speed at exactly 5000 revs. Not a massive gain, but enough for me.  If you use the "Gear Commander" website you can mess about with any front and rear sprocket configuration and read-off the speeds at any given revs in any given gear. I have seen 38 and 39  tooth rear sprockets advertised, so you could gear the bike even higher.

Has someone already changed the sprockets from standard? I've a 2015 and hardly ever feel the need for 6th...I'll check the speed at 4500 at the weekend

When i had my 2014 SX, i changed the front sprocket to a 16T from a 2006 Z1000 (Pt No: 13144-1320 £34.37) and the rear sprocket to a 39T.
