This is SupermotoXL's secret body render stage 1, the purpose of chroming the body serve two purpose. To detect mesh 'crack' and check deformed or uneven surface. Later from stage 1 to stage 3 the shiny chromed surface will be tamed via partial conversion to glossy surface to capture the most needed surface for templating the body which match the legendary silver and gun metal color looks. I call this technique as "XL Phantom Render". The legendary NEMIXIS XL-XGT also produced in the same way too.
