Banshee R6 and FZR based racebikes in the #300 wet range without going all CF. How much the counterbalancing, R6 transmission and the cases to go along with them will add is likely to be a few pounds.
I completely understand not jumping in the deep end too early - I think they are talking about a year away
i'm also waiting to see one then maybe thinking about it. i'm also thinking about a 2017ish Kalex Moto2 and putting one of these in it haha. they sending out any updates to people on the list? i've seen them post all of about zero about it in the last year.
BRC have bikes running with their big 2T single. It is fuel injected too. People may know them as the company that made a updated version of the 256 Rotax 250cc GP bike engine.
From Facecrack, probably some delay due to rona and some due to the popularity of the 500kits. https://www.facebook.com/story.php?id=100076524294155&story_fbid=433512325876240
Here's a dude in the USA making TZ250 billet crankcases and putting them in an R6 chassis: https://www.facebook.com/OttoDEM
They put out teaser on FB every couple months. Apparently starting to come together. We're downsizing to 1 truck and 1 bike next year. This would likely make it 2 bikes.
