I went out and measured my Baja 4+1 and come up with exactly 2" right on the line in the manner you requested.
For reference my OEM fronts measured 2 1/4" and my Douglas .190 3+2 measured 2 1/2".
Current quads:
- Honda TRX 400EX - fully built 416cc motor and full XC racing setup for fast trail riding and hill climbing
- Kawasaki Prairie 650 - work quad for around our property and main quad for the wife to ride
- Suzuki LT80 - kids quad
- Honda TRX 350RX - my old school hybrid MX quad from the 90's that has a 250R chassis with a built 350X motor and has now been converted into a XC setup
Previously owned several other sport quads and a few trikes over the years.
