About compatibility between the piston
set, connecting rod set and crankshaft
(by model year)
MODEL Piston Set
2015 2CR-116A0-70
2016 2CR-116A0-71
Piston set:
The piston and piston ring of the 2016 model
is different from that of the 2015 model.
As the 2015 and 2016 models are not
compatible each other, be sure to use a
combination of a piston and a piston ring of
same model year.
Since the piston set of the kit consists of
pistons, piston rings and piston pins, the set
enables installing those items on any model-
year engine at once.
Connecting rod:
No change.
Crankshaft:
As a thrust bearing is added to the #4 cylinder
for the 2016 model engine, the 2015 and 2016
models are not compatible each other.
Since the 2015 model crankshaft is not
available in the 2016 model kit, purchase a
Yamaha genuine part when a 2015 model
crankshaft is needed.
