Matti Seistola’s mechanic sheds light to the details that turn Sherco’s SE 300 into a race-winning weapon in the Enduro 3 title hunt.

In only his second season on Sherco’s two-stroke bike the likeable Matti Seistola managed to get a win in Enduro 3, on day two of the EWC GP of Chile. It was Sherco’s first victory in the world championship that along with Matti’s top results in the following rounds of Spain and Portugal have made them serious contenders for the E3 title. But an injured finger in Greece left Matti riding with pain that dropped him to third in the standings. However, after the halfway point of the season, Matti’s still in the hunt for the title.

Mauro Cremonesi has been Matti’s mechanic from back in the days when they used to work for Husqvarna’s factory team. Since 2014 they are both part of Sherco CH Racing. Talking about the team and their relation to the French factory, Mauro says:

“Our team’s headquarters remain in Varese, Italy. That’s where we do the logistics and the service to the bikes. All major modifications to our bikes come directly from Sherco’s factory in the south of France. We all visit the factory at the beginning of each year and spend some time with Sherco’s engineers testing new bikes. Overall we’re really satisfied from the job done there.”

“We started working with the Sherco SE 300 in 2014. There were many things to be done and overall I’d say we didn’t do that bad. But for 2015 we’ve really made a huge step forward regarding bike development and that can be also seen from Matti’s results. He’s quite happy with the bike so results are finally coming his way.”

We caught up with Mauro Cremonesi during the EWC GP of Greece asking for an insight on how Sherco’s SE 300 was transformed into a winning machine…

1. Suspension

“Sherco has a great collaboration with WP suspensions. We use the 48mm WP Cone Valve forks along with the WP Trax rear shock, which we modify internally. We’ve been working for a couple of years now with Matti and we know exactly what he prefers. He has a really smooth riding style and prefers his suspension being soft and progressive. We’ve also cut the subframe a bit to lower the rear part of the bike by 10mm. This helps Matti get a bit more traction out of corners.”

2. Engine

“Our major goal is to have plenty of power and torque in the bottom. We run a different cylinder than standard and we sacrifice some of the engine’s power in high rpm to have a smoother and better power delivery from low rpm. All engine modifications are done in Sherco’s factory. We collaborate with Fresco, an Italian brand that builds exhausts according to our needs. Both our pipe and silencer are enduro-specific and developed especially for Matti’s bike. We’re planning to introduce them in Sherco’s official racing parts catalogue soon.”

3. Electronic Power Valve

“Together with the factory team we’ve developed special settings for our electronic power valve system. The goal again was to have power from low rpm. We’ve tried several solutions but ended up with just one specific map that Matti loves. He uses it in most races during the season. We keep the switch for choosing between two separate maps and we place it behind the headlight. But Matti rarely uses it. When we started working with the two-stroke we have more options to choose from, but we decided to make things a little simpler for Matti this year and it seems to work.”

4. Crankshaft weight

“One of the first things we do to every new bike is to simplify its electrical system by removing some cables. That helps reduce the overall weight. Overall we don’t have a really light bike. I think our SE 300 is somewhere close to 120kg without fuel and that’s mainly because we’re using a bigger crankshaft in the engine. There is some added metal parts in some different places in the crankshaft and that’s also done for giving us more torque in low rpm. It’s another modification that comes straight from the factory in France.”

5. Cockpit

“I’d say Matti likes his bike looking like a chopper. He’s got some strange settings with the clutch lever being really – really high. And the rear brake pedal stands high too. As long as that’s OK with him, we’re fine with that too. The handlebars are raised high as well. That’s something the Matti has been using for some years now.”

6. Brakes – Protection

“We’re using special factory callipers by Brembo along with extra, larger-diameter brake lines. It’s a small addition that seems to have really positive effects in Matti’s riding. We also use a floating front disk from Braking. We have an aluminium frame for the radiators, which is built by French Meca Systems. They’ve helped us for a long time now and actually the products we’re using from them are also available for any rider to buy. There are no modifications in the bike’s frame.”
