STILL butt hurt!

how does that fit with the OEM tail parts?

The only part you use is the chevron shaped fairing, didn’t try to put it on yet. Will do today.

Man, European QA/QC is garbage these days…

meh, they apologized and express shipped them today.

Overall my experience with them has been very good.

you might be the first person that has bought one of these...

There’s a guy in this thread a few posts up that says his buddy has one…but yeah, I guess they haven’t sold many yet, at least not in the North American market.

You could sell a stock tank and almost recover the cost…

They had one job haha

What are the advantages of this tank? I get that it may provide lower cg but according to Bruce, that might be more a hindrance than anything. Basically, you don’t see superstock/superbike teams with these on their bikes.

Actually you do see them with tank like this, they are just custom fabricated from metal and a much higher cost. The ergos are WAY better, you move around on the bike easier, you get further off the bike with less effort, and the tuck position is easy and ergonomic.

It’s not so much about lowering the center of gravity as it is about moving the center of gravity toward the back of the bike, which IS advantageous.

So it’s mostly about ergos, partly about improved weight distribution.

And they are using modern technology to make getting this settup cheaper than custom fabricating an aluminum tank and tail section. The plastic unit costs less to produce, is easier to install, and is more crash resistant and easier to replace.

I think of this tank like my Sicom Rotors without the crazy costs and waiting period as the Sicom Rotors…it’s just technology involving into something better.

Kramer is already doing tanks like these OEM, I suspect that you will see more manufacturers doing these as OEM over the coming years.

So to answer your question, the reason to do this tank is the same reason WSBK bikes do them, except manufacturing technologies have evolved where we can now get WSBK style tanks and seating/tail sections.

Everything else aside you'll be able to climb around more readily and hang off farther and get less fatigued doing it. 2 seconds a lap on a 2 minute lap.

And if the CG's too low you can raise the bike then move the swingarm pivot down to get the same anti-squat. This thing is calling my name. I hate the shape off the stock tank.

Steven how much gas does it hold couldn't find anything on their website? From a maintenance standpoint it's 916esque. You're to the back valve cover in 5 minutes.

The WSBK tank requires WSBK level setup. It also has a, WSBK swingarm, different forks, mass damper in the tail, and a lot more range of adjustments.

And if it’s such an advantage why are WSBK teams running alu tanks opposed to these?

If you want to raise cg without altering geometry, you only have about 5 mm to work with. Whether that’ll be noticeable or not is unclear. Would be interest to hear of @Calderara di Reno’s friend’s experience with it and what adjustments were made to accommodate it.

I hope it works out but seems like a lot of work for an unknown benefit.

I think they said 19 litres in the video, assuming I heard him correctly.

That’s probably part of the fun of trying these things for the OP, although I thought the potential benefits are clear (ergonomics) rather than unknown.

If it does make it easier to move around and to hang off, etc, then it seems pretty cool and I’m looking forward to seeing what he thinks when he’s been able to try it.

It’s a fun thread and I always like it when other people spend their money to try new things.

Out at Chuck this weekend? Looked for ya last SoCal round but didn’t see your truck. And where the F is @Jolly Roger V4 ? No latte jokes in a long time

Man true story, I loaded my truck for that Friday session, then got a call on a big fire to put out at work that was gunna cost me just enough money where I couldn’t logically go to the track and push it off…was so annoyed at loading the truck for nothing that I didn’t unload it for 3 days.

Bike is apart right now, my next scheduled track day is January 13th unless I get everything buttoned up for some of the December dates.

Believe it or not it only took me 20 minutes to take the tank and rear tail section off the bike, very straight forward project. Will take me about the same amount of time to put the new tank on, if that.

Arguably getting it painted and getting the newer 2023 fairings is a fair amount of work, but it just takes money from me not time.

Honestly it’s not an onerous project, pretty fun to dig into actually

Rules might specify an aluminum tank.

Negative. Tanks can be made out of composites but need a fuel bladder in them. Aluminum tanks don’t

I don’t know if the ‘negative’ applies. It’s apparent your Google search revealed using a non aluminum tank is problematic, or at least requires some level of additional material to be compliant. Adding a bladder to a CF tank may remove whatever weight benefit there was in using it in the first place.
