Comparison of Bimota YB 11 Nuda and MV Agusta Lustale

Strip community

When two divas of the two-wheeled upper class get rid of their haute couture fumble together in order to openly present themselves to the public, the pleasure of undressing has reached a new dimension.

There were times when model athletes only felt obliged to "faster, higher, further". They are over. Gone are the epochs in which the figure was emphasized, but without revealing details during the competition or afterwards. The era of unrestrained undressing quickly dawned. Ice skating icon Kati Witt presents himself naked in Playboy, entire women‘s national teams publicly show what they have, men’s teams no less and Triumph stripped the Daytona to the Speed ​​Triple. So it’s not surprising that even an aging model athlete like the Bimota YB 11 wants to start a second career without a shell after the conversion by the German importer ZTK. Or the well-trained racetrack starlet MV Agusta F4, animated by the committed dealer, unrestrainedly Lust sweaters.
The way in which the two once fully disguised present themselves naked is of course different. While the Bimota unabashedly presents what was not originally intended for the public, the Lustale maintains an air of decency and covers its neuralgic areas. Brushed stainless steel sheet, carefully shaped and set, hides the view of the fuse box or cooler sides. Also on the air ducts to the airbox, which are much shorter than on the production motorcycle because the modified fairing is eight centimeters higher and closer to the steering head. That looks ?? apart from the original lower radiator hood ?? quite stimulating and by no means frivolous or even cheap.
In this regard, the bare YB 11 looks like the Reeperbahnspelunke next to finer clubs in Paris’ Latin Quarter. Even robust minds turn red when looking at and through the bare frame, find the unsteady cooler just as unaesthetic as its meandering hoses and the poor fit of the cockpit interior trim. That catches the eye and initially hides the view of those subtleties with which Bimota has always known how to shine. Tea filigree wheels, for example, the rocker mounts milled from solid, a posh triple clamp and a footrest system. Or the unique monocoque as tank, seat and rear paneling.
Ultimately, the obtrusive nudity of the good old Yamaha FZR 1000 engine and its ancillaries dominates. It was not built to show, but to grab? and he still understands this discipline masterfully today. 136 hp and 103 Newton meters are a full life, especially when they are handed to the wide Streetfighter handlebars. Even if the stage for undisguised performances is as inhospitable as when you made contact with MOTORRAD. Ice and snow, gravel and road salt: Not only the bare bike aspens, but the rider too. But it is precisely in these situations in which the wide handlebars, the generous torque on the engine side and the decisive commitment in the low rev tidy come into play.
In contrast to the filigree MV, a short pull on the wire is enough to drive the Bimota out of the corners with power, the transmission usually has a break, the driver can concentrate fully on the choice of line. The lustale, however? the basic bike of this conversion is a first generation F4S ?? is undisguisedly bitchy, has not followed the progress of later years. She is delayed and then accelerates all the harder, needs at least 4000 rpm to even go forward, then another 3000 turns to get a breath. To finally ?? then usually already in speed ranges that trigger speed traps on public roads ?? to show what’s in her. The 750er marches between 7000 and 13000 rpm, what it takes, this pithy suction rattle, the brilliant propulsion and the hoarse hissing from the four tailpipes in the rear frame condense into a breathtaking triad. No question about it, this engine is designed for the racetrack, it is too good for the low revs. And works hand in hand with the chassis in this regard. Because even if the Lustale is now directed via a shortened Ducati Monster handlebar, the following still applies: the otherwise unchanged F4 chassis can always unfold when it is really sloping and really fast. The Lustale, on the other hand, acknowledges unmotivated rolling with the rear section having to get used to it.
With the Bimota, the situation is exactly the opposite. The stern is initially neutral, only to sway when it is leaned under tension. This is by no means the fault of the fine Ohlins shock absorber (ZTK offers a variant with a Paioli shock absorber for 9499 euros), but rather a common suspect: When the YB 11 appeared, the Michelin Hi-Sport TX 25 was up to date, and its flank was already up Back then it turned out to be very unstable and buckled slightly when accelerating hard. Nothing has changed to this day. Also not because the paioli fork traditionally appeals to be chewy. Here the Lustale has a clear advantage. Just like when it comes to braking. Which is not to say that the Brembo system in YB 11 is toothless. For reasons of age, however, it cannot possibly come close to the level of the formidable Nissin facility in the MV.
S.o Public nudity does not only create conflicting feelings among moral apostles. The Lustale is beautifully made (and can be wrapped up again if necessary, because all original parts are included in the price of 24,990 euros), but the engine does not meet the expectations of a Streetfighter drive in this prototype. Dealer Lust (phone 0221/93707070) promises remedy for the future by means of a shorter secondary translation. The YB 11 Nuda, on the other hand, offers a rustic strip, but the right drive for the purpose. In addition, it is available from ZTK (telephone 05193/9640) in a wide variety of expansion stages and for a whole 10,499 euros.
