Description

Gearshift lever BGM PRO SPORT for Vespa Smallframe PV, ET3, PK S, PK XL, PK XL2/FL2/HP

BGM PRO has given the successful shifting claw BGM6550 an update. The successor BGM6555 has a completely redesigned detent profile. Thus, the gears sit even more precisely and the dreaded gear jumping is completely eliminated.

The BGM Pro shift claw is made of high quality 15CrMo5 (SCM415) chrome molybdenum steel and is therefore very resistant. The flanks are, compared to the other shifting claws available on the market, very tightly toleranced. This allows the claw to be accurately guided in the main shaft, effectively preventing skewing/tipping.

FIT FOR
The BGM Pro shift dog is manufactured for the so-called PK gearbox type. This is driven with the round type shift claw (length of 50mm (overall height)). Round type shift dog means that the pins that engage the gear wheel are radiused at the transition to the end of the arm.

IDENTIFYING GANGWHEELS
The PK type can be recognized by the marking on the gear wheels. This always starts with a 42xx (=round gear claw with 50mm). The old type is marked by the number 37xx (=cornered gearshift claw with 51mm). The easiest way to recognize such a gearbox type from the outside is the conventional rear wheel nut with M16 thread and safety cage including split pin. The old engines (with the previous type of gearbox = 51mm claw / square) has only a M14 castle nut with cotter pin (without safety cage).

ALSO USABLE V50/PV/ET3 from 1976
The PK gearbox version was already used in the last years of the V50 (V5A1T from No. 69444), V50 Special (V5B3T from No. 94315), V550 Elestart (V5B4T from No. 1514) as well as the PV125 (VMA2T from No. 150203) and ET3 (VMB1T from No. 8161). The shifting claw can of course also be combined with the main shafts of the older engines (M14 thread), if at the same time the gears of the new gearbox type (PK marking 42) are used.

PURPOSE OF USE
The BGM Pro gearshift claw is designed for racing and has been used there very successfully many times. However, it can be used without further restriction in everyday use and also convinces there with its high quality, a perfect gear change behavior and a very long durability.

COMBINATION
The BGM PRO Sport shifting claw is perfectly matched to the combination with the BGM PRO gear wheels as well as the BGM PRO main shaft. However, like all BGM PRO vehicle parts, it has been designed strictly for backward compatibility with stock parts.

CONCLUSION
The new BGM PRO SPORT shift dog offers a high standard of reliability and improves the shifting precision as well as the durability of the smallframe gearboxes.
