Everything should bolt right up, the bolt patterns are the same:smile:

 

[milo raptors]

the 160 head has smaller valves

 

[Strigoi]

everything will bolt on. the 160 head has a smaller combustion chamber than the 200 head too.

The 160 head has a smaller combustion chamber than the 200 head too.

Which can be a positive, correct Strig?

 

[Strigoi]

yes, it ups your compression which gives you a bit more power.

 

[chadillac]

so the valves are smaller. will that afect performance

 

[Jdominique]

Intake 25 mm
Exhaust 24 mm

I believe valve size is the same for both 160 and 200.

N-R Racing lists all parts for the 160 and 200 together.
