The Beta EVO Mk2 was the fruits of our ongoing work through out 2010, and finally saw the light of day at the final race of 2010 at Phillip Island.
Major changes included:
- GP style reverse cone exhaust pipes - custom made by Beta Engineering
- Carbon front wheel light weight components
- Highcomp Pistal pistons
- A windscreen!
Mike has been thinking about these pipes for ages, and finally after the 4th round of the nationals we got a chance to get them all up and running. You can see a couple of pics here of work in progress. The first one clearly shows the cone of the megaphone attached to the new header. The second one allows you to use see the reverse cone attached to the end of each megaphone. Sufice to say starting it like this was to say the least FARKING loud!The header pipes are 2inch stainless with an internal diameter of 48.5mm. Length is 24inches. The megaphone and muffler sections are aluminum. The muffler sections are added after the reverse cone so to not effect the tuning from the megaphones. We tuned the header length with the 900i.e camshafts in mind, however we never got around to installing them.
These pipes added a staggering 6HP to the midrange of the bike, and completely filled in the 5800rpm hole that the existing 2 into 1 pipes had made. Peak horse power was only increased by .5HP but that was not really what we were after.
Here is the completed pipe ready go on the dyno. For the dyno results have a look here.

Carbon front wheel and Light weight components

| Narrow band rotor |
Snow flake rotors: 1666gm
Narrow band rotors: 1354gm
Saving: 312gm per rotor, total saved 624gm
Front axle
I ordered an aluminum front wheel axle from the awesome Ducati Kaemna team in Germany
Standard steel axle: 351gm
Aluminum axle: 164gm
Saving: 187gm
Aluminum exhaust brackets
Also in the Ducati Kaemna catalog where these amazing little units to remove the cast iron exhaust flange. Talk about light!
Standard flange: 254gm
Aluminum flange: 51gm
Saving: 203gm per flange, total saving 406gm.
Milled triple clamps
In an effort to lower the bike we milled 5mm from bottom of the upper triple clamp. This allowed us to raise the clamps by 5mm with a spacer on the steering stem, in turn allowing us to lift the forks in the clamps by 12mm in total. The required milling provided us with some weight saving.
Standard clamps: 651gm
Milled clamps: 606gm
Saving: 45gm
Total weight lost: 1.2kg
Highcomp Pistal pistons
Windscreen
Mike had been giving me a tough time about a sad aero dynamics of the bike. That was primarily because I am a fat bastard. So given we where off to Phillip Island for the final round I made a screen up from some 2mm perspex. This took a while using a heat gun and a lot of time, drilling and bending and swearing a lot. Apart from getting burned from the perspex a few times, and going nuts when the perspex bent the wrong way I took me about 3 hours to make. Top speed at Phillip island was 227kph, not bad for 78HP.
