LT 2-Ring Piston LTP-A Ø37.98 - for Simson S51, KR51/2 Schwalbe, SR50

LTP-A pistons 37.98mm LTP-A pistons are completely redesigned and optimized in all points for Simson cylinders. - Extremely lightweight - The lightest pistons for Simson on the market - Extremely resilient: The inner geometry of the piston and the alloy ensure stability - Very wide piston shirt at the inlet: Good piston guide even with very wide inlet channels - With piston window: Thanks to the Window Better cooling of the piston base and additional filling of the overflow - no clamps: very precise piston geometry specially tailored to the thermal expansion for air-cooled cylinders - rattle-free: high-quality 1 mm steel rings in precisely manufactured piston ring grooves - LTP-A 2-ring piston for series and sports cylinder - LTP-A 1-ring piston for tuning and racing cylinders Geometry - A Diameter: 37.98mm - W Length: 50 mm (like Original Simson S51 and Co.) - C Compression dimension: 31 mm (like original Simson S51 and Co.) - D Ring joint distance: 2 mm - E Ring joint distance: 2 mm - F distance of contact surfaces: 15.5 mm (fit for 1 mm thrust washers) - G diameter Piston pins: 12 mm - H Wide piston shirt Inlet: 33.5 mm - I Wide piston shirt outlet: 28.5 mm Weight Piston (basic size): only 55 g Weight Piston incl. bolts, rings, clips (basic size): only 70 g Scope of delivery - LTP-A piston - piston pins - piston rings - piston clips Hint: LT know-how Langtuning constructed the LTP-A pistons from the ground up. Length, diameter, etc. transmitted to the manufacturer and the manufacturer produces a piston shape. These shapes usually have a high material thickness and the piston is therefore correspondingly heavy. Langtuning is breaking new ground with the construction of the LTP-A pistons. This is of course much more complex and requires appropriate experience. However, this means that the piston weight is an average of 10% lower than usual pistons in the quality price segment and around 20% lower than the cheap standard pistons. At the same time, the pistons could be reinforced with an appropriate strut design, depending on their size, so that they are not only lighter, but also more stable. The LTP-A pistons are optimized for slot-controlled Simson cylinders. Thanks to an extra wide inlet shirt, very wide inlet channels for tuning cylinders are also possible. At the same time, the LTP-A pistons are also suitable for standard cylinders and can be used without any problems. The piston windows are positioned in such a way that there is no short-circuit with the inlet or side outlets.
