Back in the shop

There’s no special sauce in that edge, it’s got a titanium crank and some titanium bits in the top end to handle higher RPM, but it’s essentially sort of normal run of the mill endurance racing parts

With Ducati’s, the entire bike is built around the engine, the entire chassis of the bike is set up around managing that engine. HP for race is like the KTMRC8C. It’s chassis first engine second.

Which is precisely why they’re so damn good to ride at track, especially if you’re not a professional

Iirc it uses titanium rods. I don’t know of any engine with a titanium crank.

Folks keep saying there are people capable of rebuilding these motors, but no one seems able to name anyone. As with many things - lots of talk. lol

There is a racing team that has a shop in South Carolina called KWS that builds/re-builds the engines. I’m pretty sure Attack Performance can too but will call them to find out ;-)

At 146kg there is nothing else like it.

Apparently that’s the dry weight. 171kg fully fuelled from what I found on the interweb. V4R with the Akrapvovic is apparently 179kg wet without fuel, and that’s with the stock fairings and sound deadening, etc. It’s a significant difference in weight of course and it’s definitely a cool bike.

For apples to apples comparison with full gas tank the V4 with a lot of weight reduction is still about 35 to 40 pounds heavier.

spooky said:

Yes, it’s a significant difference, I just wanted to clarify the earlier 146kg comment - dry weights don’t really mean all that much.

I agree. As long as you are comparing dry weight to dry weight, I don't see why dry weight would be problematic.

Get one, but get the Kramer not the KTM…you have to go through Kramer for any support on the bike and parts, and it has a slightly better ECU.

Almost no tangible difference between the bikes, but back end support is phenomenal with Kramer and non-existent with KTM

Unfortunately, 200-ish km in, on the start of my 3rd day on Mugello the engine blew up, briefly seizing on the main straight (much for the fun of people coming behind me) and spewing oil thru the vent hose in the air box.

Following in the footsteps of Steven, I did get a Kramer. It’s a really beautiful bike.

Waiting to hear from Kramer if they’ll pick up the bike (it’s kept in a warehouse in Germany) and look at it or I am on my own
