If a crankshaft with a longer stroke is used, this additional stroke has to be compensated for for two reasons. On the one hand due to the mechanical conditions to prevent the piston from hitting or the engine runs too highly compressed, on the other hand to keep the control angle of the cylinder, which determines the performance, within a reasonable range. If the stroke is extended, [...]

Those who convert their GTS to handlebar end mirrors can use these covers to make the existing mirror holes disappear. So everything looks like it was at the factory again. The carbon style variants are a special option.

The BGM Superstrong for Lambretta already has a "built-in" clutch compressor system. The Superstrong coupling can be easily compressed with just two screws and long nuts. On the face of the coupling spider, two of the legs are marked with a point, at the bottom of which is the threaded hole for the screw. Here the screws are used for pre-tensioning [...]

Plastic storage dummy. This allows the crankshaft to be mounted and moved in the engine housing on a trial basis and without any effort. Thus, for pure measurement purposes, neither the crankshaft nor new bearings are stressed. Ideal to control the control angle of the crankshaft (rotary valve inlet) or the cylinder (exhaust angle, overcurrent angle). Made in Germany (US) bgm - Item number: BGM1204TL Availability: in stock (Please check the [...]

PRIMARY KIT BGM PRO EXTRA LONG Motors with a lot of torque and an early power peak choose the straight-toothed clutches that also require a straight-toothed primary gear (also available as a set with clutch). This enables very long reductions to be achieved. Also perfectly suitable if the overall transmission ratio is changed in very sporty engines with a modified auxiliary shaft and shorter gear steps.

High-precision BGM PRO auxiliary shaft axis for the bearing of the primary drive of the Vespa PX125-200 models. Here in a complete set including bearings, bearing needles and circlips. This means that a secondary shaft can be completely re-stored. We recommend the BGM locking set (BGM6503NKT) to secure the auxiliary shaft axis. For a comprehensive overhaul, we offer the primary repair kit from BGM (BGM0195F48). This contains reinforced [...]

Installation information: The coupling tiller and base plate can only be installed in one position. To do this, orient the spider to the base plate in such a way that both the lower and upper spring pouches of both components are aligned. This prevents the clutch springs from being misaligned, thereby ensuring that the clutch functions properly (see also PDF under "downloads"). As a lubricant, we recommend [...]

Supplementary tool for BGM8811N. Can only be combined with BGM8811N and then offers a clutch compressor suitable for the Vespa Smallframe models. It is possible to replace the clutch linings with the clutch mounted in the engine. Blocking the primary to loosen the coupling nut is not necessary with this method. The springs remain installed when the pads are changed and the Sisyphean work keeps the springs [...]

BGM clutch pinions are bulletproof. Developed for the enormous power and torque of today's engines, they are made from high-alloy steel (SCM415 / 15 CrMo 5) according to the highest manufacturing standards. The extremely high strength of the base material (up to 1100N / mm2, HRC 58-62) provides a reassuringly secure basis for the production of BGM pinions. The production meets the high [...]

The BGM PRO 177 piston rings are extremely break-proof, have very little friction due to their coating and are very torsion-resistant. With a thickness of 1mm, they are also suitable for very wide and high outlet shapes. The rings are packed in pairs. The piston rings with 63,0mm diameter also fit: 177 / 187ccm Parmakit 177 / 187ccm Polini Alu 177 / 187ccm Pinasco [...]
