The Royal Enfield 570157 Lay Shaft Sub Assembly is a genuine Royal Enfield gearbox component used in the UCE transmission gear train.
The lay shaft is a key component of the motorcycle gearbox assembly and works with the gearbox gears and main shaft to transmit engine power through the selected gears. Royal Enfield parts catalogues identify 570157 specifically as “Lay Shaft Sub Assembly”.
The exact part number 570157 is listed for multiple Royal Enfield UCE models, including Bullet 350 UCE KS, Bullet 350 UCE ES, Electra 350 UCE ES, Classic 350 and Classic 500 EFI. Parts listings also identify applications including Bullet 500 UCE, Thunderbird 350/500, Continental GT and other UCE models.
This complete sub-assembly is suitable when rebuilding or repairing the UCE gearbox and is an ideal replacement for a worn or damaged original lay shaft assembly.
