I noticed that the new 1000cc Mudpro appears to be built on the extended TRV chassis.

It would be totally cool if all it needed to be a 2-up is just the purchase of a rear seat, then you would have it all...1000 (950) cc's, fuel injection, power steering, big tires (and the proper gears to match them) a snorkel and a seat to have your mudbabe ride along with you.

Anybody know the bottom line on how this is built, and whether it would need many mods to add a second seat

 

i don't think u can put the rear seat on it but im not 100%. i believe the reason for the longer wheel base is for water riding (water wheelies). and the 1000s do not come with power steering as far as i can tell. there are some extreamly knowledgeable people that could answer all of your questions on the high lifter forums, they are all about mud riding over there and are very into their mud pros in the ac section. also i read a forum over there debating weather it is the trv chassis or not too it is longer but idk if is the actual trv chassis or not.

Make sure you get extended warranty if you buy an arctic cat
I got the 5 year unlimited km on mine ($1500CAN)
Glad I did!

 

The widths and wheelbases of the Mudpro 1000 and the TRV chassis are the same.
Wheelbase = 58" and Width = 47.5 for each. (the TRV's body is longer overall, but that is only because of the rear rack behind the TRV's rear seat)

Based on those specs, it would only make sense to me that Arctic Cat is utilizing a well designed and rugged chassis (and one that is already developed) by using the TRV chassis for the exact reasons you quoted...stability in mud riding, especially with a hogdaddy 950 v-twin. If you look at the body work of the Mudpro 1000, the footwells are the giveaway that they are using TRV body panels.

The rear seat for a TRV works off the same speedrack mounting points as shown for the rear rack on the Mudpro 1000.

It was more wishful thinking about the power steering...was hoping if a system fit the 700 chassis, it would fit the 1000 chassis, but the V engine may cause clearance issues with a PS setup.

Honestly, it would really be cool if the reduced gearing on the Mudpros was available for retrofit on the non-mudpro ATVs of the same size...it would be nice to be geared properly to turn 28's. May just post that idea itself
