BMW nineT: Carpi Moto, in collaboration with Matris, has developed a specific suspension kit.
Having purchased the nineT, we drove the winding roads and scenic highways of Liguria. At first glance, the suspension was not up to the bike, especially if you consider the price range at which BMW sells this Café Racer.
The fork and steering damper do not, in fact, offer any adjustment, and the rear mono shock absorber is the typical basic OEM shock.
The road test confirmed our suspicions: before changing or adding accessories on your nineT, you need to upgrade the suspension.
Forks: The main problem is that they have no hydraulics. It is possible to adjust the spring preload, but in practice you cannot adjust anything. All the work is done by the fork springs. When you brake, the forks compress all the way, and you feel the roughness of the asphalt. The front wheel does not absorb the road like it should, making your ride less pleasant, and leaving you with the feeling that something is not perfect but there is no way to change or improve it.
We have therefore developed a fork cartridge kit that will provide the adjustability of a high-end set of forks.
The road test with the upgraded forks has proved us right: now the front wheel is firmly planted on the road, the turn-in and cornering are significantly better, and the vibrations are practically non-existent. This Matris fork cartridge kit offers the same quality as the best aftermarket complete forks.
Update February 2015: we have introduced a new upgrade to the cartridge adding a Sport version which has a +15mm stroke, also we have installed the fork not leaving any mark, the result is a bit more handling and less load on the front.
Steering Damper: Why would the nineT require a steering damper? Our opinion is that the front will lighten too much at high speeds. Exceeded 140 km/h, air is felt on the chest and the helmet, the rear OEM shock compresses, and the front wheel raises. Therefore, in the case of head-shake or vibrations, it is essential that the steering damper keeps the handlebar firm. Over 200 km/h you must hold on tight and say a prayer (we arrived at 220 km/h and then let off the gas). Unfortunately, the stock steering damper is not able to counteract the vibrations. You need a professional product like Matris. On our bike we installed the top of the range: the Matris SD-R. Adjusted properly, we got the correct set up and are driving in complete safety with a big margin.
Mono Shock: The stock shock works directly on the swingarm without any linkage. It's the classic, cheap OEM shock, and it is not rebuildable.
We asked Matris to produce a compact, high-performance shock absorber, which would be fully adjustable. The Matris engineers exceeded our request. Their shock settings include : High- and Low-speed compression, height adjustment, rebound damping, as well as integrated hydraulic spring preload.
All adjustments are easily accessible and customizable. The system is so compact, there are no nitrogen chambers or knobs attached to the frame of the bike, and the rear frame can still disassembled as per the nineT style. We also changed the color of spring to silver so it would match perfectly with the swingarm and the nineT spirit. (You can also order the spring in other colors.)
The Matris shock does not include a mud guard, but we were able to re-used the stock mud guard. Please note this work should be done by a suspension workshop only and requires a specific tool.
The road test with the Matris shock was exciting. The bike now travels like it's on a rail. Out of the corners, on the gas, the rear is no longer pumping, and the tire stays planted to the road. In chronological order, after the fork cartridge kit, this is the modification that we recommend.
