Yeah, R for race, S for street...but I'm pretty sure the R comes with lights....at least the prototype models on the Brammo site do (green bike is marked at SMR).
And not sure a few lights = 2k in higher price...
Thinking maybe, MAYBE...big big guessing here....that the R will have smaller battery that is swappable...the S will have a larger battery that is not swappable (racing could benefit from swapping...street riding not so much)....so street model is better for commuting and some fun off road riding...range similar to Plus...say a 4-5kwh battery pack vs 6 for the Plus. 70-80 miles of commuting...a bit less than an hour of wot off road riding.
Race model is better for off road riding and some city commuting...but keeps smaller swappable pack for fast changes at races. Pack is 3 to 4 kwh giving 40-50 miles of commuting or 30-40 minutes of WOT off road racing.
Now this is all guessing and very very VERY likely WRONG...
Waiting on info and specs and time frame for delivery....still most likely getting the plus...but the idea of a dual sport bike is interesting....
Went over to zero and checked out their bikes again...range just seems too short and I've never loved their styling...
Of course my dream style bike would be Brammo making a triumph t-100 clone electric bike...I could try to do one as a conversion but I would surely electrocute myself...and don't call me Shirley.

(make an electric as pretty, iconic and functional--bench seating for 2--as this...hard to do as the engine and pipe actually add to the beauty...but if it was easy then anybody could do it
