If you're riding a Yamaha R1 or YZF-R1 from 2009, 2010, 2011, 2012, 2013, or 2014, this Caltric kit has got your drivetrain covered.

It's a brand new, complete set including the drive chain and both sprockets (front and rear, though the placement is specifically for the rear sprocket).
\n
The whole setup is made from steel and comes in that classic steel color.
The chain is a 530 size with 122 links, and it's a non O-ring type.

It's built to be strong and reliable for your ride.

The sprockets are designed to fit perfectly with your bike's specs, so you're getting a direct replacement that'll bolt right on.
\n
Everything's manufactured in China and comes with a 90-day warranty from Caltric.
It's a great way to refresh your bike's power delivery and get rid of that worn-out chain slack.

Just a quick note for California folks: there's a Prop 65 warning attached to this.

But for everyone else, if you're looking for a solid, no-nonsense kit to keep your R1 running smooth, this is it.
