2018/19 4t Race Rear Fender

[xdab]

Will fit on 2017/18/19 RR-S without modification?

[Darkside]

yes. they are all the same. only difference is the shrouds. 18's don't have the vent holes

So, just to be clear. Can fit 2018/19 4t Race plastic onto 2017 RR-S; shrouds, sides and rear fender.

[Darkside]

yes. replaced all the plastic on my 18 390rrs with a polisport set from rmmc with 14-17 plastics. they are also interchangable with the 2T plastics

Does your bike have the tool kit holder behind the left numberplate? If so, you need to buy a new airbox to go with the new-style (no numberplate) rear fender.

The switch in the other direction is easy to make.

You're right TW. Thanks for heads up.

forgot about that. my 14' 300 and 18' 390 are interchangeable. I think the rrs changed in 19 and the 2T's changed in 18

Will be replacing RR-S airbox to facilitate newer RR plastic. Anybody done this and can caution me about anything squirrelly I should anticipate, i.e.... required new clips, disconnecting and reconnecting electrical that was really intended to be ~ "permanent", weird fitment issues, etc....?
Have removed rear fender assembly which wasn't a big deal but was more involved than expected so just wondering if indicative of a major pain when removing subframe and wrestling off stock box.

Piece of cake. Upgrading to late model short fender plastic (2018-2019) requires new air box but install is no biggie. A relatively inexpensive restyle option. For whatever it's worth.
