I saw a REV 440 in Quebec City without the hinged snowflap, it looked like a long track but no it's a 121 inch.My question is why, I think it looks better.

Don't know exactly why the 440 model has, what i think is "the better snowflap" and the rev 600 and 800's have the other style, but i guess the 600 and 800 is designed that way to kick up more snow on the heat exchangers.

Hopefully the 600 and 800 snowflap will have a little better design in future,...IMO!

ANYONE, please correct me if I'm wrong ;)

can you imagine racing with the beaver tail?it would get destroyed on the snowcross circuit,it does look 100% better without the tail IMO :p
