Do we need it for the f2 if we go down -1 and +2. i was told that on the f2 in wasnt needed

 

i dont think so cause the speedo is connected to the front tire not digital

 

speedo is completely mechanical off the front wheel, a speedo healer wouldn't work and is not needed for gearing changes

 

thats what i thought. so there you go..... nope not needed

 

what is a speed healer?

 

Its for the bikes with electronic speedo's, everyone who does a gearing change should get one because without it you'll get a false readout, that obviously would get worse at higher speeds. There are a few threads in the 600RR forum about them.
