S&S have been offering their big bore kits for Sportsters for a while now – to take an XL883 up to 1200cc, or an XL1200 to 1250cc if you’re feeling ambitious – but having looked again at the whole line, they realised that they had to make them more affordable.
Each kit still comes with the same high quality liner inserted in the cast aluminium barrel – in black or silver – a high compression piston, rings, clips and all gaskets, but have managed to shave $200+ off the price.
Kits are available for most Evolution Sportsters as are S&S’ Hooligan kits for 2000-on Sportsters. They include S&S’ 482 cams, premium followers and deliver a bolt-in 80% increase in power and a massive increase in torque–using an S&S intake and exhaust.
The 1250 Hooligan gives more power and torque across the board but is only suitable for the bigger motor as it requires the XL1200’s heads.
