SHde, a few yrs back a buddy of mine had two 400 foreman and as did I, and he wanted to take his THEN girlfriends oldest boy out riding with us,
so, he claimed he taught the kid out to ride, shift and all that, a 16 yr old boy, that RODE a MX bike with a manual clutch
well, the kid drove the foreman in second gear all day long, never KNOWING< or so he said that he had to shift it?
he never shut it off and was in second gear when my buddy gave it to him to ride
we rode about 25 miles up and down hills, and all he did was FULL throttle it every , where to TRY to keep up
we thought he was going slow, due to new to atv's LOL
was super dusty, so we all kept a good distance to NOT eat dust so much, and with helmets on, we couldn;t hear that poor motor screaming
SO< as I said, a TACH,
MAYBE seeing the RED line and lights a blinking would have helped, NOT SURE on this kid!! he wasn't sop bright!
but its NOT the first time I heard of NEW RIDERS not SHIFTING, PERIOD, or just not shifting when needed , or ???
a tach would just be another tool to help teach a rider to ride better
not all riders grew up on tings like we did to know better, and HOW to use our ears to tell us things going on or to do while riding!
and in todays world of SO many blasting music while riding, I doubt nearly as many are learning WHAT A motor sounds like , to KNOW when it NOT running right or when to shift too??
you would almost think that so FEW wear helmets they would actually hear better, learn there motors better, but??
