I ended up getting a front and rear rim, just the rim, from my friend last night off of his 2013 KTM 450SXF. I brought them to work and weighed them on a much more accurate scale. So the front rim is going to be 1590 Grams/3.50lbs. The rear is 1880 Grams/4.14lbs. I also brought in the forks off of the same bike and weighed them. They are filled with oil and have titanium springs. The left side with the caliper bracket weighed 4445.21 Grams/9.8lbs. The right side weighed 4411.21 Grams/9.72lbs. I also brought a brand new, non O-ring DID chain. It is the DID ERT2 Gold. It was 1356.241Grams/2.99lbsI will have data for a set of my billet aluminum X-Trig Triple clamps asap as well as better data on a full set of front and rear wheel assemblies. Ill try and get any other weights you'll need as well. Appreciate all of your hard work.edit: oops I may have pm'd you this same info Piboso. I started typing it up on my phone and wires got crossed somewhere lol.

The math is simple from there
