    I feel the stock gearing on the TS660 is way too short, to the extent that 1st gear is almost unusable.  Today, I replaced the stock 16T sprocket with a 17T.  It has had the desired effect.  I can pull away in 1st without feeling the need to shift to 2nd almost immediately.  There is a considerable difference, and I'm very pleased with the result of this simple mod. Of course, it will also have the added benefit of revving lower in 6th gear during highway riding (once this bike is broken in!)   In case anyone else is interested in doing this mod, I used a JT Sprockets JTF565.17 which I bought on Amazon.

    do you still like the higher gearing?  I only have a few hundred miles on mine and typically shift 1-3-5 since it's so short...

    Absolutely.  For me, it was a game changer, the first and best mod I did to my bike. Inexpensive and it lengthens the gearing to how it should have been from the factory, in my opinion.

    I tried searching Amazon for that part number and could not find it.  Can you paste a link here?

    I got it from Amazon Canada, but it now says it's currently unavailable.  I'd contact JT Sprockets direct: http://www.jtsprockets.com/

    I found this one on eBay, same part# so obviously used on multiple different bike brands:  https://www.ebay.ca/itm/263754232549?hash=item3d68fa32e5:g:PKoAAOSw9mFbID16

    Somebody posted on another forum that they used a PBI brand sprocket: part# 756-17  Might be worth contacting them to see availability.

    Man... 17t out of stock at Amazon.ca and fortnine.ca too.   I even tried the dealer today and they also can't find any stock.  I guess I'll wait and do it when I can get the part!

    I contacted JT Sprockets directly the other day, and got a reply from Bike Alert, which I think is their distribution arm.  They said that they are out of stock, but they are on order.  Couldn't give a delivery date yet.  So at least it looks like there will be some in production, hopefully soon.  I want to buy another, to have ready for when it comes time to replace my chain\sprockets. Yes, I do intend keeping this bike for a long time!
