Dyno test Sherco 250SE-R 2023 with VHM cylinder head

[@salvatorebondi706]

power to the shaft or the wheel?

[@mikeconnor2102]

Well if you look it's a rear-wheel Dyno so you can pretty much assume it's to the rear wheel

[@iktorn3539]

Next yz 112 or rm 112 or other 112cc

[@legendhvh1239]

Please dyno the SHERCO SEF300 4 STROKE

[@derek3107]

40hp

[@_Alex_250]

Are the 49hp on the wheel or on the shaft?

[@OleMisss]

That’s wheel horsepower. These newer two stroke engines make serious power.

[@tromppis7031]

@@OleMisss wrong, the numbers shown are corrected to engine=shaft power. VHM has stated that in the comments of multiple videos.

It's a pointless test as is the 125 tested, unless you state the combustion chamber volume of the original head, and the VHM head insert, along with the compression ratio and squish clearance.
