92 honest-to-goodness rear wheel horsepower in a perfectly set-up package that weighs less than 300 pounds. Arguably the fastest DB1 in North America and likely the only one set-up for serious track day work.
Noted moto journalist, Chief Instructor at Yamaha Champions Riding School and Sport Riding Techniques author Nick Ienatsch rode the bike at Mosport last week and had this to say: "Buy it. My experience on Steve's DB-1 at Mosport couldn't have been more positive. He rolled it off the trailer Saturday morning, we rode the hell out of it all weekend, and he rode it back onto the trailer Sunday night. All Steve did was add gas. Bulletproof and extremely fun, surprisingly quick...probably the fourth-quickest lap time in the fast group at DOCC. The motor pulls strong, the bike sounds right and the chassis is sorted and composed at the limit. The problems? All the new sport bikes in the way during lapping!!"
The machine started out as a pretty tired and far removed from stock DB1 that was brought over from Europe by the previous owner and as such, it made an excellent candidate for a full-on hot-rod. The bike was completely stripped-down and I started on the process of renewing all the rolling chassis components and rebuilding the motor over a period of 22 months. The end result is an absolute riot on the race track – really sharp handling as would be expected with a platform as short as the DB1, but with excellent stability. With 93hp and 63ftlbs of torque, the little bike goes like a scalded cat. Given that the Montjuich cams are being used, I would have expected a more peaky delivery, but the Meyers Performance 790 kit beefed-up the bottom end significantly. As you can see by the dyno chart in the pics, peak torque is at 6,500rpm and there’s usable stuff as low as 5,500.
I’ve ridden the bike at the Ducati Owners Club events at Mosport in July 2013 and May 2014 as well as at NHIS in October 2013 - and have been amazed at how well the whole package worked at speed. The DB1 Is surprisingly comfortable and easy to ride fast – and absolutely gorgeous sounding. My log shows 6 hours of riding time on the motor and I just completed a full post-track day service.

Please check out the dyno pull videos at http://www.youtube.com/watch?v=_tVaaTTa3jA&feature=share&list=UULXdTYwizBnNNHuc_JRjwKw and http://www.youtube.com/watch?v=w5hU55YhUYY&feature=share&list=UULXdTYwizBnNNHuc_JRjwKw . Note that I was still fooling around with jetting in the first video, so you can see the stumble as the motor came out of the lower rpm range. The final jetting set up has the motor pulling cleanly from 4,000rpm. The 2nd video is one of the heat cycle sessions as I was breaking the motor in. You can also track the progress of the build on my blog:
And finally, there are hi-rez copies of the pics used in this listing at: https://www.flickr.com/photos/loudbike/sets/72157634524192692/ To get to the hi-rez images, select one and at the bottom of the text box on the right side of the image, you'll see an icon with three dots. Click it and then select "Download / All Sizes" and then you can View or download the original 3mb image..
There are a few surface cracks developing in the bodywork that are most visible in the hi-rez pics (it’s inevitable; the bodywork is paper-thin except in the main support area between the four mounting studs).
This is a fully-sorted track bike that’s ready to go. Add gas, tickle the carbs, push the starter button and have at it!
This is a rare and unique machine. Consider that a standard DB1 in decent shape will fetch north of $19k: add 30 reliable HP, knock almost 60lbs off the curb weight, upgrade the wheels, suspension & brakes and you get a sense for what it would cost to build this machine. Reserve has been set accordingly.
