I'm not a clutching expert but I do have a PB80 that I have tested on my 900's.

The biggest thing about the PB80 is its simplicity and ease of making changes to it (spring and weights) in order to tune it to achieve the desired performance gains.

It is very easy to disassemble and has fewer moving parts to wear out and it tends to be lighter than stock clutches.

It also engages smoother than the TRA did and that was the selling point for me. The 1200 would buck and buck with the TRA in slow\low speed maneuvers.

Easy to Clean and Adjust are just added benefits for me.

The biggest thing is its simplicity and how easily and quickly you can tune it. The 1200 loves to run at 87-8800 RPM, getting it there with the stock clutch isn't easy or cheap. Basically, compared to a stock sled, you can put this on with the right spring / weight combo for instant and very noticeable performance gains. The low maintenance and light weight are other added benefits. For the cost, it's probably the best bang for the buck with regards to performance.

The real selling point is durability...i had people coming at my booth at a few powersport show with 40000-60000km done on their pb80 without changin anything....Because tunability isnt so great..yes its easy to change springs and weight but you cannot ever change the ramp profile as in this case it's the cap playing the role
So if someone out there could change the cap? Or even machine the plastic slider\carrier.

Even more adaptability with an ease of adjustment.

Hmmm, any machinists out there with PB80s?

Not sure about long term durability for my application but I ran a PB 80 on my 2016 800 etec with great results. The sled vibrated less than the tra and had a noticeable performance gain when compared to my buddies 2016 800 etec.

Weight savings was 4 lbs of rotating mass compared to the tra.

As others have posted....very simple clutch to work on.

Ease of tuning is what sold me on them. Had to replace a broken tra on my 11 renegade and put a Bill Cudney kit (pb80 included) on it and wow, what a difference. Pb80 does it all. Easy to tune, increases performance, very low maintenance and reasonably priced. Have had 5 1200's and 4 of them got pb80's including the 1200 I just picked up in the spring.

IF you want a lil bit higher engagement and different profile there is the m8 pb80 clutch cap wich is made a bit different....as for machining the cap i'm not sure its stamped.. theres not a lot of material to work with...

I put a 700/1300 in my pb80, Dalton 50/44 helix with a Dalton red spring. Did not have this setup before winter was over (everything was stock) and am looking forward to trying this out this winter. Have had multiple Cudney setups and wanted to try something different.
What weight are you running? I'm right at 100g each puck and like I said, my RPMs are bang on 87-8800. It doesn't pull and keep pulling like my mod'd 09, but I'm more than happy with this one stock with just clutching.

I've started with 8 pucks which if I remember correctly is around 97g. No testing yet as the mods took place this summer. My 16 was fully modded with Boost's program but I decided to not go that route this time. Will do everything else I can with out touching the ecm(no header or muffler mod)

What performance changes did you realize with Boost's mod's .... quicker acceleration .. higher top end ?

I don't think it will be close to the 900T. Guys are saying the 900 will run with the 850's. The 850's are quick. For what the 1200 has, it is quick. I had an 850 and it was fast, but I am back on a 1200. Boosts program made the sled excellerate quicker definitely. Not sure on top end, never tested after the program went in. It did do 186 km/h when only clutched and geared (45). I had a few small issues after the ecm program so that is why I will stay away this time and do everything else.
