Here’s what we now know about the new Bimota KB4


Bimota was essentially born out of the need for an improved chassis at a time when horsepower exceeded chassis development for most manufacturers.

By taking some of the best sports motorcycle engines of the day and surrounding them with a premium racing chassis, their motorcycles quickly began to gain a reputation for being the best machines to have on the track. The company has seen several ups and downs since then, but their recent move to Kawasaki may well have put an end to those lows. The Tesi H2 is an engineering marvel, and now they’re going back to their racing roots with their latest creation; the KB4.

It’s a bike that’s all about handling, with the chassis once again a priority and the engine once again a Japanese naturally aspirated inline 4-cylinder.

8 Enter the ninja


For the KB4, they clearly weren’t looking for extreme horsepower, but rather sufficient horsepower. The Ninja engine delivers just that, 140 horsepower, which is actually more than enough for most.


The goal of this machine is agility, turning faster than virtually any current road bike. It also has a shorter wheelbase than virtually any liter bike, barely taller than most beginner bikes.

7 Extremely compact


With a saddle height lower than the magic bar of 32 inches, you could say that the bike is accessible, but it is not.

The price remains to be determined, but it will be in the premium category, this low saddle height has nothing to do with making the bike more accessible. It has everything to do with making the bike as compact as possible and more efficient on the track.

6 Back to their roots

With a wheelbase of just under 55 inches and the low seat height, they were able to achieve a significantly lower center of gravity than it would be on the Ninja.

Ultimately, this project brought them back to where it all began, creating race-oriented chassis that feature enhanced handling characteristics. It’s a project that they clearly spent time and a lot of money doing this bike well, and we think they were successful.

5 Custom truss frame

For the most part, this frame is quite difficult to see, hidden quite neatly behind the large fairing.


It recalls their glory days, with a design inspired by those past creations that made their name in the early years. It is understandably light years ahead of these frames, however, much lighter and stiffer than any that came before.

4 Radiator tucked under the seat

A rather odd design feature is the placement of the radiator. In an effort to keep the wheelbase as short as possible, they stowed the radiator under the seat and above the rear wheel.

Only time and a few real-world reviews will be able to tell how hot this will make the bike seat, but we sincerely hope this doesn’t end up being one of those Italian “quirks”.

3 Billet Aluminum Components


Apart from the frame, all other components are machined aluminum, from the footrests to the swingarm, the bike exudes quality.

It’s not just for the quality feel, however, it also reduces the weight of the bike. A continuation of the weight saving theme is the carbon fiber elements throughout the bike and then the icing on the cake is the leather seat which adds quality and comfort (how much comfort remains to be seen ).

2 Premium suspension and brakes

As you would expect from a high-end bike like the KB4, Öhlins takes care of all suspension components.

The fork and rear shock (especially the TTX 36) are things you’ll usually have to look to the aftermarket for, and Brembo will take care of stopping the bike. For an agility-focused bike, this is an obvious area to focus on, and they didn’t disappoint.

1 Gorgeous design


Quite frankly, we suspect that not everyone will like the fully streamlined design that Bimota ultimately went for, but it is indeed a rolling work of art with beautiful, flowing lines.


The retro sportbike theme is clearly meant to evoke memories of Bimota’s early years, and it does so quite successfully. The design work is very tasteful, devoid of any angular elements that might disrupt the flow of its retro design. If that’s not for you, well you’re in luck because you might like the look of the RC version which loses the fairing and goes full cafe racer, it’s also decidedly more angular.
