Micro vs mini
I was just wondering what the differences are I know most of the mini sprints run the 1000 or bigger motor and the micro is a 600 but what else is different? Chassis? Ect?

10" vs. 13" wheels
Offset vs. Upright chassis Rack vs. Schroeder-type steering box They're not all that similar for both being motorcycle powered, chain driven, open wheel race cars. |

All accurate. Micros have the engine offset significantly to the left and the driver's legs fit down in the chassis, beside the engine, similar to what you'd see in a go kart. Minis have the engine mounted more centered and the driver sits upright (like in a midget or sprint). Both engines are mounted transversely with the crankshaft perpendicular to the frame rails where a midget or sprint has the crank oriented parallel.
In the 80's, we called them "Mini Modifieds", "Sidewinders", and later "Modified Midgets" (i.e. National Modified Midget Association, NMMA) typically with 250cc 2-strokes and some Rotax snow mobile engines. 1200cc were "Mini Sprints". In the 90's, 250cc Modified Midgets gave way to "600cc Mini Sprints". By the late 90's-2000's, 600cc powered cars were branded as "Micro Sprints". 1200cc Mini Sprints reduced engine size to 1000cc (still called Mini Sprints) and now, they are commonly called "Lightning Sprints". |
Re: Micro vs mini
Also on the Mini sprint/Upright Mini sprint/Lightning sprint cars. Primarily 1000cc in the USA. The chassis is very similar size and wheel base to a midget chassis. Some people including me convert midget chassis over to run a bike engine and chain drive. Personally I have converted and run a 1999 Stealth Midget into a lightning sprint. Another one that gets converted a lot is the Triple X Midget chassis, but I have seen people convert a Spike, Bullet, DRC and a Ripper.
