    I know this is old. But please explain this logic. Do you think the same link would wear more than different links? I would think the opposite. And having 1 more link spreads the load out to more area-less wear.
    You've always got to bear in mind that motorcycle chains are not used in an ideal arrangement. If you designed the chain and sprockets to give the longest service life the sprockets would be far larger in diameter and the chain much heavier. That's impractical but bear in mind that the rotational speed of the chain on bike sprockets is high - too high by chain manufacturers' recommended designs - so the chain is affected by centrifugal force and moves around in the pockets, rubbing against the teeth and wearing them. This happens from day one. Chains and sprockets will always wear, even in an ideal situation.

    The problems develop with use. With a new chain all the links should move similarly so that they sit into the pockets as well as possible but that doesn't last. Inevitably some links will move less freely after getting grit between the plates and so on. That means that link and the adjacent one(s) don't sit properly and the load is transmitted over a smaller area, greatly increasing the wear rate. When the sprockets are designed so that a link and pocket only meet infrequently the wear is shared out. If that link and pocket meet every cycle the wear is concentrated so you could, for example, wear out one tooth on a sprocket where all the rest are still usable.

    I am giving my 17 tooth front sprocket an outing with my 40 rear.

    I had to remove the steel rib on the inside of the sprocket cover, which gives room for the chain to run without fowling the aluminium case. I hope the higher speed when riding doesnít push the chain outwards via centrifugal force and knacker the case or chain. Iíll give it a whirl ad report back.

    I love the 17 front sprocket and 40 rear. 3500 RPM showing for 70 mph is exactly where I wanted it.

    1st gear is now useful and dropping a cog to get the most from the torque and power is fun.

    Has it had any effect on the gear indicator, when I changed the sprocket on my 2015 it confused the gear indicator, the display  kept changing.

    Not that I noticed. Plus Iím assuming you mean the rpm warning? Which I have set to 10k.

    It was the gear indicator that tells you what gear you're in. On my 2015 when in 5th gear it would sometimes show 6th then go back to 5th , or 4th it would show 5th , the ecu works out the engine revs and the gear the bike is in and then displays what it thinks is the correct gear. By lowering the revs for the same speed it can confuse the ecu.

    Ah! Understood. No, definitely no issues there.

    I donít know what peejayís talking about, but yes, sprocket changes like this whacked up my indicator something fierce, so I got a Healtech GI Pro DS-SER G2 indicator, stuck it atop my dysfunctional Kawi one, quick-programmed it and now it works fabulous with my 16/39. Displays gears much quicker than the OEM. BTW, love my 85 mph at 4,500 rpm, but canít imagine going to a 17/40. I just got back from Tail of the Dragon this morning, needed my first gear in several corners as Iím already geared so low, any lower and she wouldnít have been able to power out of them.

    I wonder at gearing changes, not sure i would need a change from stock but i would like to hear more about the differences ..
    For example how much roll on do you loose with taller gearing in sixth say from 120kph .
    Is fifth or forth more of a go to gear for long fast passes in the mountains ?
    Considering the V1s  good ability re stock gearing for midrange acceleration in fifth and sixth between 120 to 165 kph I am curious and not ready to give that up.
    Hope this makes sense .......

       What change have you seen in average fuel economy?
