What do you guys think? Will BRP put a CVT on the 2020 F3,RT ? Thoughts?

There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.
F-3,RT CVT transmission for 2020

You'll most likely see a conversion to shaft-drive.
CVT's work very well; but they can't offer the same breadth of gearing ratios; that you can get with a conventional transmission.
You are limited by the space available for the clutching components.

..:hun:...…… I thought the CVT trans gearing / ratio's were infinite, but I've never really delved into them in detail :dontknow:...…..Mike

The gap "between" gears is basically zero, which is where the myth of infinite ratios comes from. But there is a very real top end, and bottom end, to those ratios in a CVT.
Having said that, I disagree slightly with Bob in that CVTs can give sufficient breadth of gearing ratios. I have a scooter that can go ~100 MPH that has a CVT, and the largest component is perhaps 8" diameter. On the other hand, maximum power is an issue, but given some cars have CVTs with some rather interesting belts, I'd say it is possible to have a CVT on a Spyder, and have a similar performance to the current system. Fiscally feasible is a whole 'nother question.

CVT's definitely have a place in the marketplace. :thumbup:
But for a touring bike to cruise at a more sedate rpm level: you want a conventional transmission.

No doubt: shaft drive has been a proven commodity for years! :thumbup:
CVTs can usually get to about a three to one spread between engagement: and their topped-out position. (I'm reluctant to say "top gear".)
With a conventional transmission: just keep adding gears, and changing the gearsets. Your overall range is limited only by the space that you have to work with. :thumbup:

I am ready. Have not bought a new Spyder since my 2014 and still have the 2011 in the stable.
Going to wait for bigger engine and whatever good stuff might come with it.
They are running out of time for me to jump in. :roflblack:

I'm willing to bet that they've got an automatic transmission being tested right now... nojoke

Full automatic versions of the 998SE5 have existed for years in the Aprilia. For the 1330 SE6 the change to full automatic would only require software updates. The hardware is all there but its not likely most would enjoy the results. Its a single clutch transmission, not a DCT.
