i bought 15t one from ALI.......easily fitted...no other mods...chain length was unaffected....you need a 30mm socket for the sprocket nut.....straightforward and it makes first gear usable

No issues??? What method did you use to get that bugger of a 30mm nut off?

I had to resort to some clever locking of the rear wheel to be able to lean completely on my breaker bar... :052:

I changed mine at about 8k... now at 30k... I see minimal wear. I do mostly highway thou, so very few gear changes, either up or down.

I am considering doing this to my 2017.

There is a 2017 zuma!!! damm... not down here  :005:

I order my sprocket the other day. I work super semi-occasionally at a car dealer, one of the techs said he would help me avec an air gun.

It was sold in Canada as a GW250. Mine is a 2017 but purchased it brand new in April 2019.

Over 30k, any major maintenance you have done? Have you been following along with the maintenance schedule?

If you don’t mind me asking, how many KMs on your bike? How often do you go through the front sprocket?

In total I've done just over 11,000 miles (17,500 kms?). I fitted the first 15t sprocket at less than 2,000 miles (3,000 kms) because I wasn't happy with the low first gear. I've just fitted (less than 1,000 miles/1,600kms) the second 15t sprocket because the chain was knackered and didn't want to run a new chain on old sprockets, although the old ones both looked in good shape...the rear sprocket was still the original.

I've changed the front sprocket twice, but never the rear.

Front's always wear faster, and while it's usually recommended to change both sprockets and the chain as a set, I haven't found it necessary.

So, when I see this subject, I wonder what the specs are.

Like does the front sprocket have any lateral play, i.e. needs a "filler" washer to prevent "wobble"?

Since you've changed it a few times, did you notice that the higher number of teeth is best,

or were all yours the same number of teeth?

The first 15T sprocket I bought from JT, needed spacing, as it wasn't designed for the Inazuma
The second came from China and was direct fit and had the rubber insert fitted, like the original

I find the 15T is a far better option than the original  :002:

Thanks for this reply. I still may get my hands dirty by getting a bigger sprocket.
