Yeah pretty much ground up build. It’s a 2016. Should be a nice bike when it’s done.

Here's one of the final pics of my R1 right before I sold it. Loved the kenny roberts paint scheme. I need to find one of these tank extenders for the V4.

OK after putting some track miles on the bike with the new triples, I certainly give it the full thumbs up. I am running the 27mm offset and love it. Calmed down the front end significantly.

great to hear that

so the front more planted?

and fast steering didn’t get slowed so much?

So you got the IMA? are there diferent models, or just one

So you’re running 1mm reduced offset which increased trail, leading to slightly slower turn-in and slightly increased stability - am I understanding correctly?

Stock offset is 30, I am running 27mm. Correct, better stability particularly mid-corner once you are leaned over. It "holds the line" better or "finishes the corner" better as people like to say. I do not notice a dramatic difference in turn in speed to be honest. If anything the v4 is too agile given the nose down geometry, so slowing that down a tad is not a bad thing.

Of course, every racer/rider prefers something different so its up to your style.

Not sure if you're still running this setup but if you've only reduced the offset then you haven't directly affected the trail.

I think you've effectively shortened the wheelbase and maybe raised the front a little by reducing the steering offset.

Edit. Reducing offset does increase trail

Has anyone tried to change the IMA eccentrics by removing the top triple clamp only? I.e. then pulling the steering tube up and out and changing the lower eccentric too without dropping the lower triple clamp or taking the whole front end apart?
