Compact, easy to use and allowing a quick diagnosis, series 251 and 261 have become references:
 They are used and recommended  by numerous importers, motorcycle  manufacturers and specialized magazines

   251:  Complete, compact, the reference !  

251 is extremely compact; its exceptional design allows to fit all elements of the dyno
(cooling fans, exhaust gas extraction, computer and all the accessories) in 80 square feet. .
All those elements, like all the cables and pipes are entirely hidden into the dyno structure
and do not get in the way.
The installation is very “clean”.
It is   the most widespread dyno
on the European market….

  261:  The tool for tunners  

261 is a 251 upgraded with the Fuchs Eddy Current Brake , controlled by the Fuchs KHEOPS software,

It allows  to carry out real road simulations (slope, aerodynamic resistance…), and to program completely automatic driving cycles. It is also the state of the art dyno for remapping ECU, thanks to its extremely sharp RPM adjustment. N.B. : load sensor is standard with all dynos with Eddy Current Brake !
A  cooling channel  is also available. It cools down the Eddy Current brake by extracting hot air.

(See Eddy Current Brake section)

It is the    tuners’, developers’ and manufacturers’ favourite tool !
