This 12 months all the Betas beget contemporary radiator shrouds that are a diminutive bit narrower and sleeker.

The Scurry Version is $10,399 whereas the identical outdated Beta 300RR sells for $9899.

The motor is in some other case the an identical as the identical outdated RR. The large deal for us is the 36mm Keihin PWK carburetor. It feeds a motor with a bodily adjustable vitality valve. It has a counterbalancer, two mapping alternate options and a hydraulically actuated diaphragm snatch. It has developed, however that’s the an identical recipe that has dominated off-avenue racing for years.
That is roughly the ultimate of the aged-college 300 two-strokes that will also be tuned through outdated blueprint.

A key distinction for this 12 months’s Scurry Version is the KYB shock. The closed cartridge KYB fork regarded on this model a few years beforehand and that was a elementary enchancment over the identical outdated Sachs fork. Frankly we didn’t quiz to peep this type of dramatic enchancment within the rear, however we had been shocked. The Beta 300RR Scurry Version has excellent suspension general. It does a astronomical job of bridging the outlet between path driving and all-out racing. In rocks and on lifeless gallop technical trails, the bike is reasonably plush, secure and predictable. On sooner trails and whoops, it’s stage and stays up within the stroke till you settle for into bone-crushing impacts. Even there, it bottoms gently, with out a clunk or any participating jolt.

They’d a whole line of minute two-strokes that weren’t corrupt. Initially they raced the 100cc two-stroke with guys fancy Larry Roeseler and Mitch Mayes largely in opposition to Hodakas within the wilderness. Round 1975 they began the 250 mission.

The motor was fixed with the SS250 twin-sport bike, however the physique was a C & J, the fork was from a Yamaha, the shocks had been Works Effectivity and heaps others. Bruce Ogilvie and Larry received the 5 hundred, however then Larry was employed by Husqvarna, so Bruce requested me to interchange him on the Harley group. I was driving for Hodaka on the time, and as properly that they had been phasing out of wilderness racing.”

The prototype resulted within the creation of the 1978 produciton Harley-Davidson MX250. About 900 had been made, however the model was discontinued when Cagiva purchased the manufacturing unit in Italy.
