    One tooth up and the counter shaft sprocket will surely fix the 6th gear low speed lugging vibration

    the rear shock has a threaded adjuster on top of the spring, setting spring preload. this is always set by the factory when new for the loads the bike is rated at. if you are in the normal load range rider, passenger, saddlebags you should be ok with the factory setting. on most bikes you can add a little more preload to the spring, to help ride height and bottoming but honda has said on this bike the adjuster is only to set the spring preload from the factory and not to use it to preload the spring anymore.. not sure why they are saying this.. possible spring could coil bind and damage shock or spring??? most bikes you change spring preload by 3 to 4 mm. any more than that you need a different spring that is stiffer. the more preload you put into the spring to support the load the ride may get stiffer. you can support a bigger load and get a good ride with a stiffer spring with less preload. if you are all loaded up pass, bags, acc, and the bike is bottoming you will have to upgrade to a ohlins. they will build that shock to work correctly for you with fully adjustable . one thing to remember if you go up in rear spring rates you should always go up in front to balance the bike. if you don't without all the added load on the rear pas, bags. acc. the steering geometry will be off. and the front end will be to soft and dive more under hard brakeing. dale

    Can't tell if you are being serious one way or the other with the "roll eyes" smiley additions, but I'll give you the benefit of the doubt on the lugging at 3,000 rpm in 6th gear.

    Since my NC feels awesome at 2,600-2,800 rpm in 6th, and it is not lugging, I would welcome a lowering of rpm from 3k at highway speed. Conversely, I would be every bit as happy at 3,300 rpm in 6th, if I was still only doing 100-110 ish kph.

    Plus ya engine sits more in the fat part of the torque making it a bit more responsive to throttle application......

Lower speeds mean better mileage based on lower rpm and wind drag....i have done lots of experiments with this and detailed mileage records over a period of years and thousands of miles. Taller gearing works!!!

    I guess no one has done this......yet!
    taller gearing WILL get you better gas mileage, but for every action there's a reaction. you'll give up some acceleration. to each his own, but this bike already lacks punch.

    Very very strange, it deserves further investigation. Thanks!

    that was said to me about the 2011 triumph speed triple too. Didn't stop me from winding 5 extra threads on the rear preload to suit my weight.

    Yep, with the rpm down lower than normal, more throttle will have to be used to accelerate and with lazier gearing it will take longer to get in the powerband. Basically lowering the gearing (go up in the rear/down the front) produces more seat of the pants torque, better acceleration, but reduces top speed. Going up the front, down the rear increases top speed but be warned, this bike doesnt have alot of top end grunt so if you want to make it more lazy, you may get in 6th at say 4800 and it may not go anymore because it doesnt have the grunt. Mine wont go more than 5500 in 6th with only 48hp plus with my fat *** it actually needs more gearing lol!!!!!

    This bike is not about speed and quick starts....plenty of other bikes out there for that.
    Riding around at a decent speed and enjoying the ride with great mileage is what this was designed for, no matter the brand of bike they all can be improved to fit any given riders wants or needs.....that is why the aftermarker is so huge. Some folks like lower cruise rpm and the best mileage as possible....gearing changes do that. If you dont like it dont do it....pretty simple really.
