Re:4x4 sport quad?
The moment you add the 4wd drive gear (front differential, transfer case, front driveshaft) and then build the chassis strong enough to hold it together, then it would be heavy. About as light as it can be made and still be durable (and cost effective) is the Polaris Scrambler. The manufacturers just cannot go much lighter than that.
Would it be real fun if it was built? Most definately. I totally agree with you. I remember years ago thinking the same thing. Having something like a 4x4 400ex or Warrior. But in order to build something like that you will have to start looking into high strength steels and special alloys. This is to keep the extreme light weight that we want, yet still have it strong and durable. This will drive the price of the machine extremely high. Prices that the general public are not willing to spend. It just isn't profit effective for any manufacturer to produce.
