Dear users of our products bearing the brand MS KART,

for the next homologation period 2006 – 2012 we have prepared for you a new kart chassis, called MS KART RCA 26
- for the classes without gear box (without front brakes) - RCA 26 A
- for the classes with gear box (with front brakes) RCA 26 C

From this basic model further modifications may be derived according the clients‘ wishes, such as chassis for karts with left-hand transmission (Billand, Honda GX, etc.). I feel the necessity to inform that these modifications, in which the basic frame is changed, don’t have the homologation.

Our new chassis is completely different from the preceding models:

It has in total 4 stabilisers:
a) front stabiliser
b) side stabiliser
c) rear stabiliser
d) middle stabiliser (transversal – under the seat)

It is equipped with completely new brakes using the latest technology:
a) Self-adjustment of the brake lining clearance
b) Intake of the fluid just from one side, the liquid for the second half passes through a channel in the body of the brake
c) The brake pads are embedded for security reasons in the brake body, and secured with a securing bolt. In case brake pads screws are loosen, they cannot fall out of the brake caliper.
d) The brake disks are of new design, lighter, with increased cooling effect. The openings are bored directly in the ribs; this prevents the obstruction of the cooling channels for the venting of the air, and boring removes more material, and the disks are thus lighter.
e) The brake pumps have a brake fluid reservoir, feeding brake fluid into the system in case of brake lining wear.
f) There is only one pedal safety cable, with fix end caps.
g) Rear brake is embedded in a special holder made of light alloy directly on the rear axle bearing holder.

The main frame of the kart is identical for the classes A and C. For the C class, only the gear control and front brake assemblies are added.

The main advantage of this chassis is that we reached with the changed design of the front axle suspension, rear axle suspension, and changes on the frame a much better balance of the down force of the rear and front axle.

After all performed tests and the first races in the Netherlands and the USA there is a great satisfaction with the new chassis RCA 26, and the obtained times are faster than with the existing chassis RC 23 and RA 23.

HOMOLOGATION PROCEDURE

On 24 November 2005 homologation inspection of the new models of chassis and brakes was performed in our company for the period 2006 – 2012. Our company was the first manufacturer in this homologation year, where the inspection was performed. This inspection was performed by the CIK-FIA delegate, Mr. Gunter, and the SN delegate, Mr. Bárta. The completely new chassis of type MS KART RCA 26, and a completely new brake system in two versions were presented for homologation:
a) for brakes on both front and rear axle
b) for brakes only on rear axle.
The components of the brakes are the same and marked by both homologation numbers 18/FR/11 and 17/FR/11, so that they are interchangeable with the possibility of use in both systems.

The homologation inspection passed without any problem, and the delegate Mr. Gunter declared admiration for the exemplary preparation and performance of the homologation inspection.
The homologation forms are available on our www pages.

Now it remains only to wish to our chassis many victories from international tracks, and to you much satisfaction with this new model and many beautiful experiences at the steering wheel of chassis bearing our brand MS KART.

New selfadjusting rear brake. The brake fluid is passed in the channel of the brake body. The brake is located in the rear axle bearing carrier by means of a special aluminium alloy holder.

New construction of the front axle: now it has a fix brake disc and a new system of internal cooling

New brake cylinders with brake fluid bottle. These brake cylinders are made for the brakes with selfadjusting system.

New front brake - a revolutionary solution. The pistons take effect from both sides, the supply of brake fluid is made from the internal side only and it is passed through a channel inside the brake body to the external side. The brake is selfadjusting - service-free.
