Finally!

[BimotaDB4]

Well, I was finally able to get up to Pa to pick up the little Bimota; I had been waiting some parts, and was finally able to get some unscheduled down time from the store, so I hopped in the truck and drove the way up 70 to the PA Turnpike. I was on a tight time schedule, so I had to pack it up and leave. I had originally hoped to hook up with a friend of mine, but had no time.

I have had the chance to put about 200 miles on it in the twisties, so here are my initial impressions:

Cheez, is it light and small!!! Stock, this bike's dry weight is in the 360 lb range. Before I picked it up, I ordered some aftermarket stuff, primarily for drivability issues.

Before buying this little beast, Bob Smith at Motopoint let me know that "as delivered" most Bimotas needed some initial "tuning"; they often came with "issues". The Db4's in particular had some low-speed, small throttle opening roughness and the stock Mikunis were noted for not keeping synch. In addition, the stock "shotgun" exhaust was a major cork in knocking a large chunk of top end off the all-but-stock 904 Ducati mill. I had ordered some flatslide Keihins, as well as a Corse full titainum system which not only increases drivabilty, but has the added benefit of knocking off almost 30 lbs of weight (over 20 lbs saved on the exhaust, plus the airbox, evap canister, and a couple other bits go bye-bye. I also chucked the cast folding footpegs and saved a few more ounces with some billet items.) The old rubber hydraulic lines went in the can, replaced by stainless braided.

The flatslides have no choke or enrichner circuit, so starting is accomplished by turning on the fuel petcock (yep), waiting a few seconds, and then cranking a few turns on the throttle to actuate the accelerator pumps. Turn the key and the motor fires right off, hot or cold.

The Corse system is mellow on the bottom and midrange, and, as the motor is still in break-in, I don't know how the top end will sound, but if a couple of half-throttle short bursts are any indication, it should howl. It's raspy, but the tone doesn't have the hard edge that my old ST2 with the Duc carbon cans had...that thing could be downright embarrassing in town. This has more of a mellow Harley chuff on light throttle.

The clutch feel is light, but has the characteristic "jangle" when disengaged. Shifting is very smooth, and requires barely a touch, a welcome change from the stiff shifter on the ST2 Ducati.

First gear is VERY tall, requiring a bit of throttle to get things moving, but once the tach is over three grand things get busy IN A HURRY; although, with 9 or 10 year old tires, the amount of playing around I was willing to do was minimal, putting this thing on its side with less than 50 miles on the clock was to be avoided. Stock, the 904 mill makes adaquate horsepower ...the carb and exhaust changes are worth about 6-8 hp...not much by todays hyperbike standards, but then, not many hyperbikes weigh-in in dirtbike range, either. The end result is a reasonable amount of horsepower in a very light package. The big bonus is the torque...gobs and gobs of it from right off the bottom.

I fully expected the seating to be very cramped for my 6'2" frame; I was wrong. While the reach to the bars is more of a stretch, the footpeg/seat relationship is ideal; moreso than the 929rr or the ZX7r I had, though not as comfy as a friend's 955i. The buttpad used for a seat leaves something to be desired, but I guess that is to be expected in a bike like this.

Suspension is on the very firm side; the owners manual doesn't even address the 5 way adjustable forks or the 4 way shocks...Paoli supplies a separate manual for the forks and addresses service and rebuilding, but doesn't even mention the adjustments, so I'm going to have to do some research once I'm through break-in and put some decent tires on it.

Brakes are typical Brembos...and they stop right NOW. Its the same system used on my old 150lb heavier ST2, so there is more than enough power to stand it on its nose with two fingers....and on the other end is this teeeny 'lil 8 inch disk and two-pot setup, with just enough oomph to settle the suspension going into a turn, but very little slowing capability at all.

So, what we have is a small, light 900cc bike, with a wheelbase 1.5 in shorter than an R-6, double the torque, and weighing in twenty lbs less than an RD350 Yamaha....even with the hard tires, exiting ANY turn with more than 1/4 throttle nets you a little headshake as the front tire first patters over the road and then loses contact entirely as the front heads skyward. Interesting. Looks like a steering damper is in order......ohh and look, under the left fairing shroud is a bracket already in place for an Ohlins unit.

The bike flicks into a turn with no effort; steering is neutral and solid, not nervous feeling like you'd expect such a teeny bike to feel. Even on some of the choppy pavement up in western Maryland, hitting bumps mid-turn never unsettled the bike. Very confidence inspiring even with the dicey tires.

I got one of the last ones from the former importer, still in the crate for less than a modern 600 sportbike. No more Db4's, But he has a highly customized DB2, a DB4ie, a really nice Multistrada and a Tesi (but I don't think that's for sale). He's also got a few SB8's and 8R's, an SB6R, and a Hailwood Replica, along with a factory HD roadracer from the seventies, one of Gobert's Superbikes (the one he one Phillips Isle on, I think) and a pristine V-Due. He is also the new Benelli importer, so there were scads of other exotics all over the place. Worth the drive just to see all the neat stuff.

Below are the before and afters.

BimotaDB4,

Sweet little bike !!! Thanks for sharing your impression and pics.

A tri-color DB4 with these mods has been on my wish list for a few years. You luckey dog!! Thanks for the writeup.

He still has a DB4ei with lotsa titanium and CF bits, light wt mag wheels and Ohlins up front and a green anodized frame for sale with the same color scheme; really a tasty little bike. Get it while you can!

That is beautiful, or as I like to say, wicked-awesome! Congratulations!

Oh yes.....I'm well aware of Bob's inventory and have watched it dwindle. However with 3 of Rimini's fun machines already in hand, it's all I can do....in fact MORE than I can do...to keep them maintained and have some kind of personal life too.

I've resigned myself to enjoying a previously owned DB4 "sometime" in the future. For now I will vicariously enjoy your riding experience (dammit!).

Have fun!

So...what do you have?

[Bruce_Allison]

For the Ducati.MS site I don't list them on my (Chuck enforced!) signature, but for the Bimota Forum and since you asked, I'll post them:

Furano
Supermono
Tesi 1Dsr

Obviously my Bimota cup runneth over (not that there's anything wrong with that!)....so the DB4 remains on The List for now.

Welcome to the Bimota family!

'Tanks!

Nice bike!
Oh I soooo want one, too... *turning green of envy*
I may be bombarding you with lots of (silly) questions later, be very afraid...
