ZZR600 64mm stock piston complete is 168grams.
Ninja-250 62mm stock piston complete is 167grams.
I have load tables for all of these at various red lines for comparison.
If I can whittle 4grams out of the Wiseco pistons to get down to 182grams complete then at 12k/rpm it will have the same load factor as a stock 300 @ 13k/rpm. Mine is for use in a Versys-X 300 big bore so lower redline.
You can view the load table in this thread which is my other project https://www.pb-evo.com/topic/78963-z...ort-300-build/
Yes you can put the Wiseco piston on the stock rods, but I'd suggest a lower redline to avoid damage. It's the TDC inertia number you need to worry about, as that is piston weight on exhaust stroke trying to rip the rod in two. |
Tank you very much.
I can't lower the rpm cause it's for my race bike and I will need to gear longer and defeat the purpose of the mod. it lives at 12-14k
I did the inertia calculation with the 250 piston to compare and it was already at 20% more at TDC.
it's crazy, I think I have a 09 67mm zx6r piston and it's at 165g with everything on it... (0107 stamped on the top of the piston).
