A bike right up my alley!

http://www.vmcc.net/1000bikes/F1000bikesTul-aris.pdf
772cc Polaris parallel twin two stroke snowmobile engine tuned to an incredible 161 RWHP @8,700 RPM.
272 pounds all up. 1.68 LBs per HP. The 919 is 4 LBs per HP.

Detune it to a paltry 120 RWHP, add minimal lighting, a squeeze bulb horn, and slightly higher bars, and you'd have the ultimate canyon carver.

Still researching it.

If it has already been done, it is safe to assume it is possible to do it.
On the other hand, if it has not been done never assume it is impossible to do it.

Tul-aris Wins First Race and Sets Track Record
June 1st, Blackhawk Farms Raceway, Illinois. Steve Johnson piloted the Tul-aris GP bike to its maiden win,shattering the old lap record by a full second during the 21 lap unlimited GTO race. Starting on the 3rd row, in the 11th grid position, Steve moved quickly though the field, gaining the lead on lap 6. He immediately opened up a huge lead in one lap, setting a new lap record of 1:11.91, as timed by CCS officials. After 3 or 4 laps out front on his own, Steve had a 7 second lead, even while slowing the pace to 1:13s and 1:14s due to waving yellow flags and an ambulance on course. He finished the race about 10 seconds ahead of the second-place GSXR 750. Our weekend started out with the identical setup we used 2 weeks ago at Blackhawk, when Steve set the fastest time of the weekend during his run from 25th to 2nd in 8 laps. However, this weekend the weather conditions were much better, with temperatures around 90 deg F (32 deg C), providing us with optimum grip from our medium-soft Michelin Pilot slicks. A slight tire pressure adjustment, recommended to us by Tom Mason of MRT, allowed us to use a marginally harder medium-soft rear tire compound compared to what we used 2 weeks ago at Blackhawk, when the temperatures were almost 40 degrees F cooler. Even better, just as the race started, a big dark cloud moved in overhead, lowering air temperatures (which gave us more power), yet the track surface temperature remained high for optimum traction. Conditions could not have been better! During the race, Tul-aris team member Dave Heiserer and I used our HeadHunter Racing scooter to watch Steve at several points around the track. It was amazing to see how smooth and fast Steve moved through the twisty and bumpy turns. In fact, the Tul-aris's Ohlins suspension was set up perfectly and there was a noticeable visual difference in how steady the bike handled the bumps andtransitions compared to other machines. We now have the handling and traction of the bike spot-on, allowing Steve to carry huge cornering speed into and through the turns. This improvement is in large part also due to Steve's exceptional skills as a development rider, as well as his smooth and fast riding style. At other parts of the track, such as the 3rd gear turn 6, the bike would power wheelie at the exit at well over 100mph (while still leaned over!), displaying the brute power of the Hot Seat Performance Polaris 780cc twin motor. Altogether, we had the perfect package for our first win! Our tally so far for our first full racing season is:
one 1st place
two 2nd places
two 3rd places
one 4th place
one lap record (Blackhawk)
one almost-lap record (0.07sec off the record at Mid-America)
out of 8 races we only had one mechanical DNF (powervalve) and one crash (in
the rain).

I'd have to get adult depends to ride that!

As I was riding today, I was thinking!!!!!! How great it would have been if Honda had put the 919 motor in the NT700 instead of that anemic lil two lung 680cc. You talk about one nice overnighter! Oh well, at least the PCoast engine with a stroker. I love the looks, but, not ready to get a bike from the "Scooter Store" although Medicare will pay for it!

This bike is a REALLY neat build.
I read the articles in Road Racing World on it.
Most intriguing.
