With feed­back from the fac­tory team about the new tri­als range Beta have used their ex­pe­ri­ence at the cut­ting edge of the sport to fur­ther re­fine the Beta Evo range for 2019, en­sur­ing that rid­ers of all abil­i­ties can count on the best avail­able tech­nol­ogy. There are three two-stroke en­gines: 125cc 250cc and 300cc, plus the world renowned four-stroke ver­sion, which is avail­able as a 300cc and of­fers an ex­cel­lent al­ter­na­tive to the two-stroke ver­sions thanks to its user-friendly en­gine power de­liv­ery, which is wel­comed by club­man rid­ers and ex­perts alike. Evo 2T

All the two-stroke ver­sions have the fol­low­ing new fea­tures de­signed to give the machine a more tech­ni­cally pol­ished feel. The en­gines, apart from the 125cc, fea­ture a cylin­der with new ex­haust port ge­om­e­try and new tim­ing curves. Both of these devel­op­ments im­prove low-rev en­gine con­trol and sta­bi­lize the power de­liv­ery, pro­vid­ing ex­cep­tional stan­dard-set­ting per­for­mance.

A new gear se­lec­tor cam has been de­signed which was used in the ear­lier ‘Fac­tory’ mod­els and pro­vides more pos­i­tive shift­ing. An­other ‘Fac­tory’ model fea­ture is the new CDI con­trol unit now with even bet­ter per­for­mance and op­ti­mized map­ping for the new cylin­der.

The 300 4T four-stroke en­gine has also been up­graded. One of the most im­por­tant new fea­tures is a new throt­tle with a re­designed in­ter­nal ramp that gives bet­ter low-rev power con­trol. Like the two-strokes, the four-stroke in­her­its the new CDI con­trol unit with new ded­i­cated map­ping.

What's new

A series of new fea­tures on both the two-stroke and four-stroke mod­els in­cludes the fol­low­ing: New shock ab­sorber port ge­om­e­try, which is now higher and more pro­gres­sive. New shock ab­sorber pis­ton with in­creased sus­pen­sion sen­si­tiv­ity and pro­gres­sion. To­gether with the mod­i­fied spark plug ge­om­e­try the new pis­ton gen­er­ates de­cid­edly more grip, mak­ing it more for­giv­ing in the event of rider er­ror. A new pump on the me­chan­i­cal side of the front fork en­sures more pro­gres­sive im­pact ab­sorp­tion. New front fork oil, which im­proves sta­bil­ity at high tem­per­a­tures max­i­miz­ing smooth­ness. New chain ten­sioner af­ford­ing a new ad­just­ment range whilst mak­ing ad­just­ments eas­ier. The rear brake cal­liper has brake-pad anti-vi­bra­tion sys­tems which max­i­mize pre­ci­sion and sig­nif­i­cantly re­duce noise. New graph­ics and colours en­hance the ap­pear­ance.
