With real horsepower gains to give you arm pulling acceleration up the steepest mountains, these kits dominate the western mountains and blasting lakes and trails out east. Terra Alps offers a lightweight piston 870 kit which efficiently max's the airflow for this 800 cylinder and acheiving maximum horsepower. Plus the smooth running and quickness of this kit over larger displacement big bores which dont gain anymore power using a heavier piston .

Big bore kit includes boring, welding and fully porting the cylinders for max airflow. Nikasil done to our spec, honed in house, exhaust valves machined, piston kit with rings and pins, billet head with interchangable domes with different compression ratios to suite your riding areas on pump gas.
