I put a coast valve in my '04 RTV and didn't like it. But, I'm on seriously steep hills and coasting is really a bad thing. I just got used to feathering off the pedal slowly to keep the dog and family from putting their hands and face all over my nice clean windshield.
For sure, this is the way lots of US go...........Just like Zoom, I live on some steep hills and it sure is nice to have that braking.
By accident the other day, with both my grand babies on board, I was headed home downhill on the gravel road kinda fast......Yes, they pester for the speed.........Anyway, going pretty good, and out jumps one of the squirrels I haven't shot yet, let off on the throttle fully, and WOOO HA........went into the best power slide/skid I ever did.............Looked over at the girls who ride with their feet on the dash or me holding the little one back with my hand on her chest, and, after they got their breath back and color into their faces said............"let's do THAT again, Grandpa"....................
Probably left a 40' skid mark in the gravel, went kinda sideways for a bit, easily recovered by countersteering, and then a full stop............So, yes though totally helpful and I want nothing more than I have..........YA GOTTA BE CAREFUL.........IT'S A MACHINE........God bless.......Dennis
