There are several things you can do to drop weight. As mentioned above, the viper seat will drop 2.2 pounds compared to the stock srx seat, We sell a light weight front end kit in polished heat treated aluminum that drops 12 pounds without ours skis and 16 pounds with our skis. You can get a lightweight rear suspension for those sleds which is also going to drop 15-25 pounds depending on what you go with. Lightweight hood you can go with. Lots of stuff. Let me know if you have any other questions. Thanks
