Transmission failure on a Ninja H2 2016 / take care

Post by Kwee » Fri Dec 07, 2018 11:49 am


Hi everyone,

Just found a guy who have a Ninja H2 2016 and the transmission failed.

I post here because our bike have a lot in common with the h2 and i'm sure most transmission are the same.
Sure the primary ratio is lower so the transmission take less torque than the H2 but still a good amount.

Ninja ZX10R 2016 first gear max torque : 490 Nm
Ninja H2 2016 first gear max torque : 660 Nm
Ninja H2 SX first gear max torque : 625 Nm

Ninja ZX10R 2016 second gear max torque : 422 Nm
Ninja H2 2016 second gear max torque : 523 Nm
Ninja H2 SX second gear max torque : 502 Nm

I know there is a recall for Zx10r 2016 to 2018 gearbox with the same failure.



I'm also worried about flashed bike because the torque is even bigger.

Take care

Edit : 2500 miles on a 2016 bike seems a bit low to me.

I don't know the guy that made this video but he talks a lot about "putting a stretch on it" and turboing other bikes. My first thought is that he rode his H2 very hard - maybe even drag raced it. With that being said, parts shouldn't fail when run hard within spec'ed limits. But something tells me this guy may run his bikes past factory specs.....

I'm curious, does anyone have any concrete world wide sales numbers for the H2 and all its variations? Just wondering how many of these are in the wild and if this is an isolated incident....

I don't know how much Ninja H2 is sold since 2015 but for sure less than zx10r. Many compagnies don't recall products if that cost too much.

It appears the build dates for the affected ZX-10Rs is from Sept. 9 2015 until December 13 2017. According to this article. https://ultimatemotorcycling.com/2018/0 ... on-issues/

In July 2017 they realized the gears were the issue. In January 2018 they started the issue was gear strength and released the recall in early 2018.

A lot of us who preordered our bikes received them late with no real explanation of why it was taking so long to get the bikes. According to the build date thread ( viewtopic.php?f=2&t=225 ) most of our bikes earliest build dates are a couple in December 2017 and most in February. So hopefully if the same gears were being used they fixed the issue before releasing the bikes.

Also our bikes are significantly heavier. There are quite a few guys here putting down more than 200 wheel horsepower and many more miles than 2,500. I think if it was going to be an issue we'd already hear about it by now.

I know several racers out here that take brand new ZX10R transmissions starting with 2011 models and send them to Fast by Gast to get back cut. The first thing that is done by Fast by Gast is to check each gear for cracks. Many if not most ZX10R brand new transmissions have at least one gear that the check fails. Several teams in the racing community know to check their Kawasaki gears before pushing hard. It is speculated that it is a quality issue in the steel/forging process that is creating this. Hopefully we are far enough down the road with Kawasaki that they have fixed this issue with our transmissions.

It was more than a couple in December as I have VIN 72. Hopefully mine is not one to have it. I am hoping to flash mine in the spring.

In the build date thread the only post i saw with a December build date was Vcyclenuts. I know they built several in December but as far as the information posted on this forum goes it appears most of our bikes were built in 2018.
