Hands-on
the new Sherco Enduro 4.5i
Following
a phenomenal response from the Milan and Paris Motorcycle Shows at
its first public presentation, Sherco is officially announcing the
Launch of the 4.5 Enduro
|
|
|
|
|
|
 |
|
Continuing with its policy to expand
into new and different market segments, Sherco is entering into
the Enduro market with a model that has been completely designed
by the Sherco Team. Both the engine and all of the chassis components
have been designed "in-house" incorporating the most
advanced features in the industry.
In early 2000, Sherco commissioned Franco-Spanish engineer Jacques
Coll to develop a new engine for use in an enduro bike - following
the premise of "Simple, Compact and Light". Coll had
already shown his technical ability by developing the full line
of Sherco Trials engines (80 to 280cc). This new challenge in
the 4 Stroke engine world would enable him to prove the depth
of his mechanical knowledge.
The goal of the Sherco team was to expand on the success that
has been achieved in the trials market. Sherco in a few short
years has become an exemplary marquee. This new venture is a
concerted effort to develop a truly functional competitive motorcycle.
Therefore, the new bike had to be suitable for a broad customer
base. The main features; lightness, size, appearance and reliability
had to be equally appealing to both week-end riders and seasoned
professionals.
In order to provide the facility for this new venture Sherco
created a new 3200 m2 manufacturing center in Nimes (France)
that is exclusively devoted to this new market segment. The
new center was successfully launched with the introduction of
the Sherco 50cc models, which have been widely accepted and
have achieved competitive success since their release in mid
2002.
Regarding the design of both the engine and the complete bike,
the Sherco team started to work with its sights set on a wide
market segment. Trying to avoid excessive idealism, they carried
out a serious market survey in order to determine the things
that were most valued by the customer. With this in mind they
set out to develop a new bike that emphasized the positive aspects
and eliminated the negative ones. This is one of the reasons
behind the decision to create a proprietary engine design. There
is no dependency on a third party product and the developing
process becomes much more efficient since the engine is specifically
designed for the application. Moreover, any future development
will be much faster and positive. |

A top of the line bike for everyone
Sherco has not tried to create a limited edition or a handcrafted
bike. Using the most advanced ideas in the enduro field as a
starting point, the Sherco Enduro 4.5 components have been designed
to be mass produced. This is the logic behind two important
features of the bike: High Reliability and Easy Maintenance.
In sync with the competitive mentality of Sherco, the new Enduro
4.5 as been designed following the premises of lightness, easy
handling and efficiency. These qualities will be appreciated
by both professional and amateur riders - who expect a bike
that has good handling characteristics and is easy to maintain.
Unlike other bikes, which demand experienced riders and expertise
in handling, this bike will provide amateur users with high
performance from the begining. |

The engine which is a Sherco Proprietary design has the following
features:
.: Single Cylinder 4 Stroke - 448.6 cc
.: Aluminum Block
.: Overhead Cam
.: Four Valves
.: Liquid Cooled
.: Electronic Fuel Injection
.: Six Speed Transmission
.: Hydraulic Clutch
.: Stainless Steel Exhaust Pipe
.: Aluminum Muffler
.: Electric Starter with a Kick-start Back-up
The chassis of the Sherco Enduro 4.5 has the following features:
.: Chrome Moly Dual Cradle Frame with
.: Aluminum Detachable Rear Sub-frame
.: Paioli-Kayaba Inverted Fork - 46mm Diameter Legs / Forward Axle
.: Heavy Duty Aluminum Swingarm
.: Paioli Rear Shock - Gas Charged / Aluminum Body / Fully Adjustable
.: The Rear Suspension Incorporates a Progressive Linkage System
.: Disc Brakes Front and Rear - 270mm 4-Piston Caliper on the Front
and a 240mm 2-Piston on the Rear
.: Excel Aluminum Rims / Steel Spokes
.: Michelin Competition Knobby Tires
When compared to the competition the new Sherco surpasses them
all in terms of modern features, such as, electronic fuel injection,
progressive rear suspension, and a very smooth, powerful, responsive
engine.

Stefano Passeri and Maurizio Micheluz,
official Sherco rider's for 2004
Sherco has put the competitive development of the new 4.5 Enduro
into the very capable hands of Stefano Passeri who has had a
brilliant international career which includes several World
Enduro Team Championships. With his oversight and riding skills
Sherco will be officially taking part in the forthcoming Italian
and World Championship, the goal is to accelerate the development
of the new bike during the first year of its introduction. With
almost complete certainty, Passeri will be joined by upcoming
young talent Maurizio Micheluz, one of the most promising rider's
of the never ending Italian school.
Stefano Passeri the official Sherco
Factory test rider for the new Sherco 4.5 talks about the new
bike
The outstanding work that has been done by the Sherco design
team on their new 4.5 Enduro bike is really amazing. Although
this bike represents their debut into the Enduro market, it
is obvious that the people behind the design of both the new
4 - stroke engine and the rest of the bike are experienced and
qualified engineers.
The external look of the bike can't be described as extremely
innovative; however it includes the most advanced features available
in the modern Enduro market.
In my opinion, one of the key elements behind its extraordinary
performance is the adaptation of the fuel injection, making
the bike completely different from rival models. At first, the
bike seems to be less powerful, but what really happens is that
the engine power reaches the bike without any kind of sudden
jerk. It is not as abrupt as other engines, it has a much lower
vibration level and, of course, it is less annoying. The horsepower
flows constantly from a low engine speed on up to max RPM. You
only realize the enormous speed that this bike achieves when
you have to suddenly hit the brakes and try to stop.
The most striking feature of the chassis is its easy-handling
quality and its reliable performance. The bike always follows
your orders, without showing any kind of weird tendency. I am
sure that, after tuning the suspension to their taste, many
people will be surprised with the handling qualities of the
first Sherco Enduro model.
Following the experience gained in the trials market, Sherco
is in the process of reaching several agreements with importers
and distribution companies with the intention of ensuring
the presence of the trademark in the National Championships
of the most important countries.
Supermotard and Motocross versions of this bike are expected
to be released soon, the Supermotard will be released first
and the Motocross model will follow a little later. An engine
for a future 250cc model is being designed in Sherco Nimes.
Limited production will be starting in February of 2004, look
for the 4.5 at selected dealerships late 1st quarter of 2004.

Mike Valade Wins the 2004 French
Supermotard Championship on
an FRD Prepared Sherco Supermotard
50cc Motorcycle
The focus of this
article is on the FRD prepared Sherco 50cc Motorcycle

Stephane Fort, for the second year in a row, has proved
that the FRD prepared Sherco bike is an invincible contender in
the Supermotard races.
Winning the series for the second year in a row proves that the
win last year by Sherco was not a fluke. Mike Valade, a promising
young rider, dominated the 2004 French Supermotard Championship
on his FRD prepared Sherco 50. Mike won the pole position seven
times and won six of the eight races in the series.
Stephane Fort, an expert and experienced tuner, has been in charge
of the preparation of the bike again this year. In order to increase
its competitiveness, he has equipped the bike with parts from other
Sherco models, such as the recently launched Enduro 4.5. He is using
the rear aluminum swing arm from the 4.5, the 280mm front brake
from the 125 CityCorp and the four-piston front caliper from the
Sherco Trials Bikes. The rear shock absorber is a Sachs unit that
has a separate tank. The Paioli front fork has more travel - 270mm
instead of 180mm - and is also adjustable. The front master cylinder
is truly a sports model: a 16mm radial Brembo.
Once again, Fort has decided not to modify the Sherco standard frame
(he truly loves its strength and stability). All he does to the
frame is replace the stock fasteners with light weight ones and
remove unnecessary items in order to reduce the weight of the bike.
FRD engine
The engine really shows the experience and the effort that Fort has
put into this project. It has been built with Fort's own design through
his FRD (Fort Racing Development) company. Both the crankshaft and
the cylinder - created from a modified Airsal unit, with a bore and
stroke of 40 x 39.7mm (40.3 x 39 is the standard Sherco) =49cc - have
been designed and built by FRD. The connecting rod is forged, and
the bearings are more robust as their size has been increased from
17mm to 20mm. Both the exhaust pipe and the airbox - which is larger
than the original one - are specially designed by Fort. Another part
which has been taken from the 4.5 Enduro is the left radiator, which
acts as a complement to the original single unit.
The intake process is controlled by a Dellorto 28mm carburetor - with
special carbon fiber Artmeca reeds - encased in a special box hand-fitted
to the crankcase. The crankcase is more compressed due to a special
piece designed by FRD. Leonelli has also contributed to the project
by designing a special digital ignition system.
According to Fort and Mike Valade, the greatest advantage that has
helped the Sherco FRD to dominate the races is the design of its frame,
which provides outstanding handling on the off-road sections of all
the circuits, where it handles like a true motocross bike. On asphalt,
the Fort horsepower and the riding ability of Mike are more than enough
to ensure that their rivals can only stare at the back of the Sherco
FRD from a distance.

2004
Koblenz Indoor Trial
Sherco
celebrates 5 years of Trials Bikes in Germany
|
|
 |
|
|
|
| January 1999 - the first time
the brand new SHERCO 2.5 was presented to the German public with David
Cobos as the rider. The bike was also the only one to be exhibited
in Koblenz. Five years later SHERCO returned to the place were everything
began for a very spectacular trials weekend. This was round one of
the Trials World Indoor and German Indoor championship. SHERCO was
the only trials motorcycle exhibitor and sponsor this weekend. The
company provided a very special highlight for the audience: a brand
new 2004, SHERCO 2.5 was the prize of Saturday's lottery; the special
bike was autographed by Graham Jarvis, Joan Pons and Carsten Stranghöner.
After the event, the bike was handed over to the happy winner. On
Sunday Joan Pons took part in his first German indoor trial and earned
a very favorable second place, Pons is a real crowd pleaser. Minded
by his SHERCO academy pupil Christian Kregeloh, Joan was really pleased
with the warm welcome he received from the German Trials fans, and
promised to return for the other two rounds in February and March
and for the German outdoor championship round. |
