which scrambler is the best for aggressive trail riding 400 or 500?

like getting the front wheels up over stuff and going in some sticky mud!!!

I see by checking clutching specs that the 400 must make alot more torque having 55 gram clutch wieghts and running at about 5800rpm
versus the 500 which uses 47 gram weights and runs at 6400rpm??

kind of weird cause I always thought that the 4 strokes had more torque!!!

 

ur gonna want a 500 4X4 if ur going to be doing any mudd riding

 

still wonder about the clutch weights though all the snowmobiles I have ever reclutched when you add HP you never add weight in the clutch but if you increase torque you always had to add weight to keep the RPM down!!!

 

there is nothing like the power of a built 400 it will get through anything thats why polaris had that motor
in its flagship utilties it was the 800 efi of its day..

 

They put the heavier weight in the 400 and run a differant primary spring.It is to make it more rider friendly.Polaris always underclutches things.

 

I would think if you took 8 grams of weight out of a 400 the thing would tach up to 9000RPM
and if you added 8 grams to a 500 it wouldn't get much past IDLE

 

You have to remember that each part effects the other parts in a CVT clutch too.
Do you have Aaens clutch tunning book?If not get one and it will help .

 

the stock 400 and 500 are close in torque i beleive. but with clutching, the 500 is way more bottom end friendly.

get the 500 4x4 for trails

 

I would get the 400, mainly because you can mod those things to beat hi-performance quads and plus i like 2-strokes because of there peppiness.
