Driving pleasure, performance, safety andreliability are the main features of the new kart
aimed at the rental market, for both indoor andoutdoor tracks. The Tony Kart Viper is the OTK Kart
Group kart entirely dedicated to the kart rentalmarket.

The new model shares the same high quality,
construction and performance standards as
the whole product range of the group. Indeed,the latest product by Tony Kart also respects thephilosophy of being “DESIGNED, ENGINEERED,MANUFACTURED, 100% MADE IN OTK, ITALY”.

The Viper is the result of intense work
both in the design phase and in terms ofdevelopment by OTK Kart Group’s R&D
department in order to come up with aproduct able to grant top performance,driving pleasure and, at the same time,reliability and ease of management.
The endeavor to keep weight down wasa priority in the design phase to produce
a high-performance vehicle that isenjoyable to drive. Several solutions forquick maintenance have been developed
to facilitate work even for less experienced
operators.

A long period of testing led to the creation ofdriver protection systems. Tony Kart’s rental
kart introduces a double safety system into
the market: perimeter protection made frompolizene together with an innovative shock
absorber system made from polyurethane.

4In addition to these solutions, there isalso a cushioned steering column which
minimizes the repercussions of any
collisions on the upper limbs of the driver.
There is also the option of installinga Roll-Bar complete with safety belts.
As far as driving comfort is concerned,
the Tony Kart Viper has a quick control
mechanism to adjust the pedals andthe seat to cater for the different heightsof drivers easily.
The kart has been designed to offer
maximum performance on both outdoor
and indoor tracks, while maintaining driving
pleasure and driver safety.

The cushioned steering column, with its
guaranteed 5 cm controlled movement, allows
energy to be dissipated in the eventof a collision, thereby safeguarding the driver’s
upper limbs.

At the rear, any collisions are cushioned by
the perimeter fairing that it is mounted onpolizene supports with a deformable structure
and a specific shape made to absorb shocks.

8SAFETY

At the front, there is a polyurethane shock absorber, positioned inside the fairingand covered by a removable cover. This shock absorption system has been combinedwith a protective perimeter band, made from black polizene, which also absorbs shocks
and allows the kart to slide along the barriers in case of collision, thereby safeguarding
the driver.

Easybusiness
The Viper does not require
adjustments or a complex set-up.
The basic set-up defined by themanufacturer is immediately suited
to both indoor and outdoor tracks.
In this way the staff of the tracks
using this kart don’t have to takecare about technical issues.

FUNCTIONALITIES

chain

The transmission can be belt- or chain-driven.
This meets the needs of individual circuits that,usually, choose transmissions that are belt-driven
for indoor facilities and chain-driven for outdoor
ones.

The pedals are independently adjustable, thanks
to two practical levers that allow you to move themcloser or further away by up to 11 cm. Including seatadjustment, the Viper can be adapted to people
measuring approximately 150 cm to 190 cm in height.

The seat can also be adjusted longitudinally:
it can be moved to 6 positions amounting to a
total of 9 cm. There is also an optional seat booster,which can be used for drivers with a very smallbuild.

The brake system is equipped with a 2-piston
floating caliper with stroke recovery, a hydraulicbrake pump with oil tank, a self-ventilating discand a quick pad changing system.

The “Cut Off” system that the Viper is equippedwith is a mechanism that prevents the driverfrom accelerating and braking at the same time,
thereby safeguarding the longevity of the engine,
clutch and brake system.

The chassis is made from 32 mm diameter steel
tubing and has a reinforced structure resulting
from the work carried out by the OTK Kart Group’sR&D department. In particular, the “C” fixing
elements of the stub axles are equipped withreinforced ribs for increased reliability.

Low weightfor maximum
reliability
The Honda 270cc version of the Tony Kart
Viper with a belt-driven transmission(without Roll-bar, seat belts and ballast
support, which are optional) weighs about
160 Kg. It would be wrong to think that thesearch for low weight is solely driven by adesire to provide drivers with performanceand driving enjoyment that are comparable
to those of a racing kart. Low kart weight,
combined with a sturdy structure andprotection systems such as those adopted
on the Tony Kart Viper, increase the reliabilityof the kart itself.
Indeed, in the event of collisions, which arevery frequent in rental karts, the energy thatneeds to be dissipated by a lighter kart islower than that by a kart with a higher mass.
It all increases the general reliability of karts
and tracks.
