What will the leaks on the top that we like so much have. It seems that the fashion has already passed because what is carried out now is to centralize the masses and lower the center of gravity, but the keel exhausts have nothing to do against a nice butt with the huge leaks on top.
Practically all brands have used this solution at some time, and there are still some that continue to use it, so we are going to review the series motorcycles with the leaks in the tail more striking, suggestive or significant. Look to see and tell us which one you would be missing to include in this list.
Ducati 916

How could we not start with this bike? The Ducati 916 was born in 1994 at the Borgo Panigale factory with a single purpose: to win the World Superbike Championship. At that time Ducati did not sell much, but its link with the competition was so strong that they put all the meat on the grill to achieve a successor to the Ducati 888 that could take the title on the road. And boy did he do it!
With a magnificent base and evolving the 916 with experience in competition came later the 996 and 998, which extended the life of this icon until 2004 and marked the Ducati philosophy in all subsequent models (999, 1098/1198/848) up to the current Panigale.

Following the same philosophy, since 1994 a total of 11 World Superbike Championship titles for riders and 14 for manufacturers have been won. We lost the escapes through the tail when the Panigale arrived, but now it seems that we have partially recovered them with the Akrapovic that rides the 1299 Superleggera in the image and likeness of those used in competition.
BMW HP2 Sport

It may be that Bmw They seem like a bit of a pain in the ass, bulky or nondescript (to taste the colors) but what we have to admit is that they are one of those who most dare to do things in a different way. Proof of them is their traditional boxer engine with opposite cylinders, which they continue to rely on generation after generation, but also in some of the motorcycles they have put on the street. Or even on the circuits.

The BMW HP2 Sport It was one of those, let's say, rare motorcycles that left the German factory in 2008. Taking the BMW R 1200 S as a starting point, they wanted to make an effective motorcycle on the track but without giving up their hallmarks, so they started working on the road model to get something worthy of having the acronym HP in its name.

The marriage between effective track and BMW parts leads us to Öhlins suspensions on the house brand's alternative trains (Paralever and Telelever), Brembo radial brakes, a 130 hp boxer engine, a lean body with carbon fiber, 178 kg dry weight and, yes, a nice dual-outlet exhaust integrated in the tail to improve aerodynamics. Why else would it be in this selection?
MV Agusta F4 750

Another transalpine manufacturer resumed the production of dream machines in 1999. It was the MV Agusta F4 750 Gold Series, a bike that left us all with a crooked ass with its groundbreaking unmistakably Italian design. From that jewel with magnesium parts (such as the wheels or the swingarm), carbon fiber (the body) and first-line materials from Showa and Nissin, an unmatched beauty emerged that continues to this day with minimal changes.

The essence of its original exhaust with four flutes below the tail has been kept intact in the F4 series with the tetracilíndricas of liter that arrive at the present time, although with modifications to give it a more modern aspect. The round outlets have given way to four square outlets, but equally beautiful and attractive.

If you have not had the opportunity to listen to it live, I suggest you get a friend who has one, so that you can hear how the ecclesiastical organ of the world of two wheels sounds.
Honda CBR600RR and CBR1000RR Fireblade

Following the line marked in MotoGP, the Honda CBR600RR 2003 was born in the image and likeness of the Honda RC211V that Valentino Rossi made World Champion in 2001. The search for greater aerodynamic effectiveness turned the smooth and rounded lines of the CBR body into narrow and sharp with which to cut the wind.
So that the exhaust does not generate turbulence, they integrated it inside the tail and hidden by the rear wheel arch. The result was a street bike that drove all of us fans crazy with its aggressive design, its similarity to a race bike, and its delightful purr.

The Honda CBR1000RR Fireblade also adopted the same line shortly after (to inexperienced eyes they were difficult to differentiate) turning the Superbike of the brand with the golden wing into an even more effective motorcycle on the circuit and with which James Toseland won the World Superbike Championship in 2007.
Suzuki b-king

At the beginning of the 21st century, a Suzuki prototype walked through various rooms. The expectation it raised was directly proportional to the size of the exhausts it used and, yes, finally that absolute disproportion reached the street in a civilized way with the Suzuki GSR 600. A year later, seeing the good reception of the 600, in Hammamatsu they decided that would finally bring to production the Suzuki b-king in 2007, the naked version of the well-known Hayabusa.

Aesthetically they had similarities, but the B-King was a very serious bug. The 1,340-cubic-centimeter, 160-horsepower engine breathed through two exhausts that weren't under the tail, they were thrown out of it in the form of two rhomboid megaphones that were almost as wide as the motorcycle's own tank. Huge!
Suzuki TL-1000R

Superbikes used to be a minor championship, but brands have always been interested in pursuing success among the series derived motorcycle competition to achieve greater commercial impact among fans. The same happened in the United States, a focus where Suzuki tried to win over the public with a different concept so far in the Japanese brand.
In 1998 they dared to enclose the fantastic engine of the Suzuki SV1000 in the packaging of a sports bike similar to the GSX-R of the time. The result was the Suzuki TL1000-R a two-cylinder with which to run the AMA Superbike with the regulations that allowed two-cylinder motorcycles to cubic more than four cylinders.

The 996 cubic centimeter V-twin engine was squeezed to 135 horsepower supported by a massive aluminum double-beam chassis with a swingarm with lower reinforcements, inverted fork, electronic injection … They tried, but the bike did not achieve the expected results, neither sports nor commercial. It was a beautiful bike (in my opinion) with a very beast sound through those round top exhausts, but she was gastona, slow, heavy and somewhat stubborn compared to her competitors.
Triumph sprint

TO Triumph he has always liked to show off. If you have a superb three-cylinder engine to power a modern-looking sport tourer, why not bring the number three to the rest of the bike's design? A bit like the MV Agusta we saw before.

That insatiable road from 1998 looked very cool, even today it still looks like a modern motorcycle with that particular front and triple headlight (just like the watches), but the most handsome thing about that bike was the triple tailpipe outlet, very high, pointing to the sky and revealing the thermal protector without shame.
KTM Duke I

22 years ago, in 1994, KTM was already doing its thing with rare motorcycle concepts and from the hand of the Kiska studio they pulled out a strange thing called KTM Duke, in honor of Geoff Duke and powered by a 398 cc single cylinder engine and a 609 cc engine. This is how the KTM Duke 400 and Duke 620 were born.
That first version of the Duke with the single-cylinder LC4 engine was the closest an enduro bike has ever been to a naked one. Since then with the passage of time and the arrival of the KTM Duke II, also with the exhausts at the top, the concept has moved away from the trail world to specialize in asphalt.

The Duke family has been expanding, with small displacements from 125 to the large Super Duke R that ensure its continuity, but the popular single-cylinder naked medium has its days numbered with the arrival of the new LC8c engine that will mount the Duke 790, although the same on the way we recover the escape through the tail, right?
Yamaha MT-01

Yamaha gets out of hand from time to time, and we love it. The clearest example of all is when they decided to create a gigantic naked from the 1,670 cubic centimeter V-twin engine that powered the Warrior XV1700 cruiser. The Yamaha MT-01 was a huge muscle bike, with a design that was out of the ordinary even in 2005, before the crisis hit.
With the XV1700 engine and R1 parts, the result was spectacular. The design of the entire model revolved around the propeller with those gigantic buttholes from which huge manifolds came out and whose end was very high, in the side of the seat with two large circular outlets.

It might not be particularly fast (it barely reached 90 hp), nor light (245 kg dry, 265 kg in running order), nor did it have a generous autonomy (only 15 liters of tank and a lot of thirst) but its 150.3 Nm torque was very beast and its design with those guns was impressive.
