Race teams are always coy when talking about what’s under the hood, and Indian’s clever wordplay states that the “core engine” is still retained from stock, but we all know there’s nothing stock about it. For starters, the crankcase main bearings are locked into place to help with reliability. There are custom camshafts, 110mm big bore pistons and cylinders, CNC ported heads, and billet manual lash adjuster rocker arms – and that’s just what the team were willing to tell us. Other than the main bearings being fixed, there’s no word on whether the crankshaft is stock, modified, or different altogether.
