2004 Yamaha RX-1 ER for my wife and an 05 rx-1 er limited edition for myself. most of our riding will be around the farm and at around 30-50mph. maybe 5-8 miles per day. we don't very good so theres not much leaning or anything going on in the turns. we just kinda slow the sleds down and steer with the handle bars. i was getting tired of her fouling plugs on her polaris 600 triple 2 stroke so bought these 4 strokes thinking you wouldn't have to run them as hard. both have have electric start and has reverse. will these work out ok for the way we ride?
