Tacita T-Race Electric Enduro: Tested at Morocco

Tacita T-Race Electric Enduro Motorcycle Details

The problem with electric motorcycles has always been their limited autonomy and general performance. Tacita, an Italian factory, has built a brand new electric motorcycle that will bridge that gap – the T-Race.

Tacita had decided to test the T-Race in the hardest form of racing there is, the African Rally Raid. The Tacita race team competed at the Merzouga rally in Morocco November 3-9.

“We want to make sure we have a bike that will be reliable and can endure anything for our customers. Merzouga rally was a good opportunity for us to test our T-race. Our objective was to gather as much data as possible rather than results and it is mission accomplished” explains PierPaolo Rigo, co-founder of Tacita.

They asked the Canadian Patrick Trahan, a multiple Dakar (2000, 2001 and 2010) and rally pilot to be their rider for this occasion.

“I was much honored to test the T-Race. I feel like I am part of a new beginning. I have race many rally here in Merzouga, but it is the first time that I raced in silence. It was such a new experience for me; I realize that I could concentrate more on my riding. The T-Race performs like any rally bike and was very good to ride in the dunes,” says Trahan.

Trahan and Tacita team manage to make a lots of world premiere. They were the first electric enduro to start a rally raid race. They were the first electric motorcycle to traverse they entire Merzouga dunes and finally they are the first to have finish and actually win the NEW ENERGY category.

About the Tacita T-Race Electric Enduro Motorcycle

The Basis

The “Tacita project” ( from Tàcita, Latin name of the Roman goddess of silence ) springs from the desire to develop a motorbike which respects the environment and the people around us, yet being a true machine for real off-roading.

After 20 years of passion for both recreational and competitive enduro, our goal was to build the perfect electric enduro bike, which would be able to compete with traditional motorbike combustion engines, giving sensations of pure riding, yet being moved by a completely “zero-emission” electric engine.

Tacita was born in 2009, to produce a new enduro bike with electric propulsion performance, whilst being innovative and unique in its characteristics.

Since then, our effort has focused on research, engineering and design, to create an Italian bike with temperament, unique in its kind.

The result is the new “T-RACE”: passion, nature, strength, silence, respect, emotions.

Tacita T-Race – The New Standard

T-RACE is the first motorbike built step by step for Enduro riding, and for the pleasure of feeling as one with nature around us, yet its name also stands for the gentle “trace” left by the bike.

Aims: Zero emission, no noise, respecting the planet – along with ergonomics, high-tech features, long-range riding, and great fun; all packed in a “legal on+off-road” enduro bike. Satisfying these requirements was at the heart of the Tacita project.

For the first time, sharing the trail with other hikers or bikers without disturbing wildlife and without noise and pollution, has become reality.

“During the tests, we have always been approached by people with curiosity and admiration. Just a very soft sound announces the arrival of the motorbike – quite similar to that of an MBT bicycle!- which does not bother anyone, not even children. With the switch to its Eco map and trail-tyres, the motorbike does not damage or mark the ground”, explains Pier Paolo.

The result:

• high-tech design, with aerodynamic fairing and headlights
• front and rear “energy tanks”, for maximum weight distribution and balance.
• battery packs set up for a rapid change in race
• multiple speed separate gearbox
• liquid cooling with separate circuit for motor and inverter
• dynamic cooling of the battery pack
• Split single-beam large-diameter frame, to deliver excellent turning performance and straight-line track: great driveability, center-weighted balance, good ground clearance
• large autonomy with eco-friendly performance, around 100 kms of tracks travel in rally-race conditions.
• excellent traction and throttle control on slippery trails, with extended “out of range” high-revs stamina performance in race conditions
• torque power curves: Eco, Race, and Boost

Tacita T-Race – Autonomy and Handling

With more than 10 kW of maximum energy contained in the battery, T-RACE will provide a full day of cross-country with friends, even those who ride traditional combustion engine motorcycles.

With T-RACE, the electric enduro is no longer confined to town use, or enclosed bike-parks.
Lithium Polymers (Li-po) Accumulators technology, the most advanced technology available today for electric mobility, is contained in four high-strength aeronautical aluminum “tanks” (two front, two rear), which provide safety, shock protection and high heat-exchange, thus ensuring optimum cooling.

The energy tanks are positioned to achieve the perfect weight distribution, thus providing a highly effective low centre of gravity, resulting in agility and dynamic balance, under all conditions of use.

The “no-memory-effect” quality of the Li-Po batteries, along with a portable battery charger, (which can be placed in a small backpack) means you can “top up” the battery charge at any electrical 220v outlet.

Tacita T-Race – Eco Refill “T-Station”

Tacita can supply a trailer that works as a solar-energy charging station and storage cabinet. It can charge battery packs without using conventional electricity supplied by power plants.

In daylight , the solar-panelled roof over the trailer, “gullwings”-shaped to maximise exposure to solar input, converts light into electrical energy and stores new energy into the buffer batteries, usable at night or on rainy days to recharge the bike’s battery packs, independently and without generating emissions.

“The T-Race – combined with the T-STATION- is a direct and indirect zero-emission enduro bike”, points out Pierpaolo.

Tacita T-Race Specs:

Chassis/Suspension:

• Anthropometric measures – T-RACE has been developed for sizes ranging from the 5th percentile (female) to the 95th (male): these dimensions fit 95% of the current population, taken as reference. When you get on T-race, driving position, general sizing, knee-bending angle and whole body position make you feel as if you had always been riding it.
• Frame: Split single-beam, in Crome-molybdenum steel tubes 25NiCrMo4
• Ground clearance: 353 mm
• Front suspension: 300 mm, telescopic hydraulic fork with advanced axle upside down – with special surface hardening TIN treatment of the stanchions. Multivalve damping and spring for static load. Hydraulic damping in compression is given by a special valve located at the bottom of each stem, while damping occurs through the use of an internal cartridge on each stanchion. Each rod is provided with external adjusters to adjust compression and extension, and a screw for venting the inner sheath.
• Rear Suspension: 300 mm, Progressive linkage, combined with fully adjustable rear suspension unit. Compression can be adjusted to high (1.5 rpm) and low speed (15 positions) in compression, and 25 positions in extension.
• Front wheel: 1.60 x21 with Excel rim and aluminum reinforced hub
• Rear wheel: 2.15 x18 with Excel rim and reinforced hub for improved steering precision.
• Tires: FIM Enduro type, or trail type (a footprint which is very close to that of a MTB bicycle)
• Front brake: steel floating daisy disc, 270mm diameter, for powerful braking
• Rear brake: daisy disc, 220 mm diameter
• Engine brake: Regenerative braking system – to increase the range, by recharging the batteries.

Engine:

• Electric motor: a 3-phase alternate current, brushless-type, asynchronous, with internal rotor cage. This type of engine has a very high yield, typically greater than 90% at the point of use, and it is maintenance-free, since there are neither sliding contacts, or other electrical parts subject to wear, nor mechanical parts that require lubrication
• Cooling System: Liquid-type, with separate circuits for motor and inverter, to stabilize operating temperature and to allow minimum energy consumption and maximum power. The efficiency of electric motor and inverter are optimal when the operating temperature is constant between 40 and 60 degrees C° centigrade. Better cooling means greater range, consistent performance and optimal battery discharge.
• Rated power: S1 8 kW
• Peak power: S2 24 kW
• Tacita T-Race Torque mappings: Eco: for the least impact on trails; Sport: for maximum driving pleasure; Boost: 60 seconds at full power for dunes or steep climbs
• Tacita T-Race Transmission:
• Change: multiple speed separate gearbox
• Final Reduction: 13*49
• Final Drive: 520 O-ring sealed chain
• Tacita T-Race Power:
• Traction battery: Li-Po rechargeable lithium-polymer battery. Li-po batteries are the most advanced technology available today for traction batteries. They have higher energy density (167 Wh/kg) and a lower weight than other batteries on the market (lead-acid batteries and lithium-iron-phosphate) and have no memory-effect. The batteries will last for the entire life cycle of the bike. After 2,000 charging cycles, (100,000 kms approx. under normal use), the battery packs with a residual capacity of 80%, can be used on the bike, or converted to static-energy storage (e.g. batteries for domestic stand-alone solar panels).
• Number of charges: >2.000 cycles (discharge + recharge)
• Maximum capacity: 10.6 kW
• Charger: 1 Kw portable.
• Optional: 3Kw fast battery charger, to be used in a fixed location. WARNING: For safety and warranty issues, you must recharge the battery exclusively with the original Tacita-approved charger.
• Charging time: 9 hours, with the included portable battery charger (just 3.5 hours with the optional 3Kw stationary charger).
• Ecological recharge by T-Station: same operating modes of charging as via the 220V electrical mode.

For the first time, enduro enthusiasts can enjoy the freedom of riding a consistent zero-emission power tool, which can really broaden the range of offroad riding to a new level.

The T-Race can fill the gap between the riders’ wishes for performance and the true pleasure of safeguarding the precious planet we live in.
