how much lighter is the 120 in comparison to the 150 ? specs on the yamaha site say it's dry weight is 589 (the Mnt. se) and the Apex mnt. SE is only like 5 lbs heavier....LOL That's got to be a crock . How much lighter is the front of a vector compared to an Apex ?

I believe they said the Vector engine was 22 lbs lighter than the RX-1 engine. But the Apex engine is 7 lbs lighter than the RX-1 So the Vector engine should be about 15lbs lighter than an Apex engine. They are both approx 1000cc. Keep in mind the Apex chassis is lighter than the Vector Chassis, more titanium, more magnesium, lighter hood, lighter battery etc.... I would say they are pretty close, My Apex and my wife's Vector feel pretty close actually I think mine feels a lot lighter (thanks to the rider forward) in the bumps,

yup it all got to do with the lighter parts on the rx1 & apex mostly a-arms & rear suspention parts lighter batt & box.my vector motor weighed 100lbs the rx motor is 120+ pounds have never seen the apex motor weighed.very easy to make the vector lighter mine weighs 535 with oil & coolant with the stock rear suspention in it it will come in close to 500 pounds when iam done this summer.
