Road Test

Motosprint 1991

Launched in February 1989 and immediately sold, the MX-R Top Gilera Endurance is the evolution of the previous MX-1. In the field of strategy Gilera 125 Sport for 1989 was twofold: first, the MX-R suitable for sixteen more peaceful and the other unpublished SP01 designed for racing in the Sport Production and suitable for most geeks. Unfortunately for Gilera, this strategy was not rewarded by the market: an ever in the market for 125 and an identity crisis of the Gilera brand brought serious financial problems. Problems that will become every year more 'important to the acquisition by Piaggio in 1991 and the definitive closure of establishments Arcore in 1992. Although with a new full fairing, a new headlamp with dual light move and some technical refinement, although the MX-R is not valid can help improve the balance of the Gilera. A pity.

The MX-R remained in the list until 1991.

Price in 1989: 5,600,000 pounds

Available colors: Black, Red and White.

The bike soon

The MX-R, especially in black color, has a line rather attractive and imposing, yet elegant and definitely less noisy certain replicas produced by competitors. Compared to the MX-1, as amended by Gilera stop at the front. We see such as:

Adopting a completely new hull sealed profile optimized to improve rider protection from wind and increase the flow of cooling air to the engine. The side air intakes to help evacuate hot air from the radiator.
Adoption of a new bigger and protective fairing that houses a new and beautiful light fixture double round. The bizarre decision to eliminate the Plexiglas dome (choice that took on Cagiva C9) which precludes the possibility of sight and therefore lie in the hull and then to seek the maximum speed, otherwise the incident safe.
New mirrors very beautiful in design, but not very useful because the lack of visibility offered.

Confirmed the solution of the fake tank that hides a practical oddments compartment can accommodate a full face helmet. Instrumentation and electrical controls remain unchanged.

Except for air intakes on the side panels slightly larger group codon-side panels with two tailpipes and the saddle remain unchanged compared to the MX-1 and is' a pity. In fact, if the line of the tail was already understaffed compared to the general size of the MX-1, MX-R, equipped with a hull even more imposing, and the 'even more.


There were no changes compared to the MX-1


The engine of the MX-R undergoes few changes from the MX-1. We see the changes made:

New cylinder
New exhaust system and carburetor different
Leaving the sporting ambitions to SP01, the MX-R engine modifications aimed at establishing a greater roundness of operation, rather than the pursuit of maximum power. The data collected indicate a maximum power to the wheel 26.48 bhp at 9750 rpm and a maximum speed of 156.5 km / h (e 26.01cv 156.600 km / h, the MX-1). For the final shot, the engine of the MX-R shows a slight improvement on the MX-1 and confirms the goodness of the changes popping up on 400 meters from 50km / h, a time of 20.259 seconds at an output rate of 93.75 km / h (20.587 sec 91.370 km / h, the MX-1)
