What is the ULTIMATE Snowbike? Pt. 2

Is spending $30,000 on Snowbike really worth it? How much power do you actually gain for that kind of money...
Last year we compared the 450 vs 500 on a hill climb. This year we take it up a notch and test out our 490 vs our 550! We also run a 450 & 500 with them to give a more accurate test as to which Husqvarna snowbike pulls the hardest and what our personal preference is. Overall the 500's out pull the 450's on a hill climb but other aspects of that Husqvarna snowbike make us question if it's worth the extra power.
To make the comparison as equal as possible both 500's have Aro 3 Timbersled kits and the 450's have Riot 3 Timbersled kits.
