Beta is an Italian motorcycle manufacturer, specialising in off-road motorcycles. Beta is best known for their popular observed trials bikes. In 2005, they launched a range of enduro motorcycles using KTM engines. In 2010 they launched the new RR series, with a new engine made in-house. Beta motorcycles have been used by world trials champions such as Jordi Tarrés, Dougie Lampkin, Albert Cabestany and Enduro riders Steve Holcombe and Brad Freeman. Production in 2018 was expected to be in excess of 20,000 motorcycles, ranging in size from 50 cc to 480 cc.^[1]

History

Beta has its origins in 1904 as a bicycle manufacturing company named "Società Giuseppe Bianchi",^[2] originally based in the town of Via Bellariva and later moved to Florence. The name Beta comes from the initials of Bianchi, Enzo and Tosi, Arrigo who ran the company at that time. Currently, the company is run by Lapo Bianchi great-grandson of Giuseppe Bianchi the company founder.^[3] The company started making motorcycles in 1948. Focusing on two-stroke street bikes through the 1950s and 1960s, the company began development and production of off-road motorcycles in the late 1960s with the introduction of the 100 cc motocross model XC-100 in 1967.^[4] The off-road models were initially observed trials bikes.^[5] In 2004 Beta entered the 4-stroke enduro market with bikes using KTM motors. By the 2010s they were producing both two-stroke and four-stroke off-road bikes with Beta designed motors.^[6]

Notable Beta riders include Jim Pomeroy, Gilbert De Roover, Ivan Bessone and Jeremy Van Horebeek in motocross, and Jordi Tarrés and Dougie Lampkin in observed trials. Beta motorcycle riders Steve Holcombe and Brad Freeman collectively have won the last five (2017–2021) EnduroGP Enduro World Championships.

Enduro models

2004-2009 Beta Motors

Introduced in 2004 the chrome-moly framed enduro bikes (with Beta 250, 400, 450, 525 RFS motors) came equipped with Nissin brakes and rotors, Marzocchi forks, and a Sachs rear shock.

For 2007 the RR models were upgraded with a removable clutch sub-cover, upgraded front fork settings, and a redesigned rear swing arm.

2008 introduced the RS models built for the American market. The RS model is the street legal version of the RR model and came in 400 cc, 450 cc and 525 cc versions.

2009 saw the introduction of the first "Factory" or Race editions. The race edition included upgrades such as a titanium exhaust, Marzocchi closed cartridge forks, billet triple clamps and a carbon fiber skid plate. 2009 was the last year of the KTM motors.^[9]

2010-2014 1st Generation Beta Motors

Starting in 2010 in-house designed carbureted motors appeared in their enduro bikes. All 400 cc, 450 cc and 520 cc (actually 498cc) four-strokes have DOHC, separate engine and transmission lubricants, Nissin brakes, Brembo hydraulic clutches, Excel Takasago rims and six-speed gear boxes.^[10]^[1]

2011 saw the introduction of the in-house motors in the RS (dual-sport) models and introduced the 350 cc motor. RS bikes have slightly different frame geometry resulting shorter wheelbases (58.1 vs 58.7 for RRs) and lower seat heights (36.6 vs 36.8 for RRs). All RS dual-sport bikes sold in the United States come standard with the TrailTech Voyager GPS.^[11]

The 2012 motors were available in 350, 400, 450, and 498 cc. 2012 also saw the introduction of the Sachs forks and rear shock on the RR models. A 2012 only cross country version of the 450 was offered with Marzocchi closed cartridge forks and a Sachs rear shock with a special link for longer travel.

2013 saw the introduction of the 300RR 2-stroke sporting Marzocchi closed cartridge forks and a Sachs rear shock. The 350 RS sported 45 mm Marzocchi USD^{[note 1]} forks.

2014 saw the addition of a 250 cc motor to the RR 2-stroke line.

The 2014 "Race Edition" bikes made use of 48 mm Marcocchi closed cartridge forks.

2015-2019 Improved Perfect Displacement Motors

2015 saw the introduction of new engine displacements. The 350 remained the same. The 400 was reduced to 390, the 450 reduced to 430 and the 498 was reduced to 480 to provide the same horsepower and torque as the 2014 models yet with more “useable” power. Beta engineers call these the "perfect displacements.” The RS (dual-sport) models were available in 390, 430 and 500 only. 2015 also saw the introduction of the x-trainer 300 cc 2-stroke employing oil injection. Fuel injection was introduced to the 350 cc 4-stroke.^[12]

2016 saw the addition of the 350 to the RS line. Oil injection was added to the 250 and 300 2-strokes. The remaining 4-strokes 390, 430 and 480/500 received fuel injection. All 4-stroke models now come with plastic skid plates and translucent fuel tanks.^[12]

In 2017 all bikes gained the convenient push button electric start. The RS models are rebranded RR-S and gained USFS spark arrestors. The bikes designated RR-S are full-on versions of their electric start, fuel-injected, four-stroke dirt bikes, outfitted with the bare minimum required for a license plate. RR race edition bikes gained the new Sachs closed cartridge forks. Beta also introduced lithium-ion batteries, while the RR-S models became electric start only with the option of an add-on kick starter.

2019 saw the introduction of the carburetor equipped 200 to the RR 2-stroke line. All models of the RR line 200, 250 and 300 gained electric start. The 125 RR-S gained electric start while 125 RR remained kick start only.^[9]

Through 2019 all RR-S models included an AGM battery, a 200 W stator, handlebar-mounted ignition map switch, fold-away mirrors, and a factory-installed radiator fan. The RR models are the "race editions" featuring performance tweaks and stiffer suspensions but no street gear.^[10]

2020-Present

For the 2020 model year Beta revamped their "Perfect Displacement" four-stroke once again. The new motors alter the crank shaft position and add twin fuel injectors allowing implementation of specialized EFI mapping to increase engine performance and mixture control. The 250 cc and 300 cc 2-stroke motors (including X-trainers) gained a counter-balancer. The "Race Edition" RR bikes were offered with optional Gold KYB closed cartridge forks.^[9]

The 2021 200 RR Race Edition, drops the oil injection in favor of pre-mix to shed weight.

2022 models saw only small changes.

2023 Saw the reintroduction of the "RR" models into the US market after six years of only the RR racing editions being offered. All Beta four-strokes gained traction control in addition to dual mappings. Compression and rebound performance was improved in the Sachs ZF forks.

2024 dual sport models were renamed back to the original RS designations. Other changes include: new radiators to improve turning radius, softer seats, improved front brake lines and upgraded Sachs front suspension.^[13]
