This was my first bike and I kept it to mid 88. It never let me down and with a knoobie it would go all places our 90 trail with dual ranges could go. The only bad thing was the was the pegs were attached as one small bolt held the assembly together and if you were climbing and went air-born it would shear when you land then you would Nut your self as least or loose it as your feet get planted in the ground. The hills at North Lake held no trail the 50 would not cover, as well if not faster than all to the 185/dual. My climber then was a KZ500 tripple no clutch one gear and 13 fr 264r it would climb any thing to including trees.
