Yes I put a 43 teeth on the rear, helped in traffic, roundabouts etc but the bike lost its relaxed 70-80mph cruise on the motorway so I changed it back.
It's more of a success on the older 1000 as they have the over drive top gear the Veek doesn't have.
Some folk like it, only way to find out is try it, a gearbox sprocket can be had for 15 quid or less of ebay.
