QR Code Link to This Post
Selling my Righetti Ridolfi Extreme 4-Cycle kart with Briggs & Stratton LO206 engine. This is a complete, turnkey package with approximately 1.5 hours of total run time. Essentially new, just without the new-kart price.
I went all-in building this correctly and bought everything new, so the buyer does NOT have to spend weeks sourcing parts, figuring out gearing, clutch setup, chain, mount, exhaust, sprockets, stand, etc.
It is assembled, sorted, and ready to drive.
KART
• Righetti Ridolfi Extreme World Formula 4-Cycle Chassis • Full-size adult chassis • Briggs & Stratton LO206 engine • Hilliard Inferno Flame clutch with needle bearing • 14T #35 clutch driver • Heavy and light clutch weights • 50T, 54T, 58T and 60T rear sprockets • #35 high-performance chain • Senior-spec header with mounting bracket brace • Chain guide and chain guard • LO206 air filter • Aluminum engine mount • Catch/overflow tanks • Upgraded hardware and exhaust components • Magnetic oil drain plug • Mounted wheels and tires • SunF K001 tires — 11x7.10-5 rear / 10x4.5-5 front
EXTRAS / EQUIPMENT
• IM Stiletto One Man Kart Stand • Extra sprockets for different gearing • Extra #35 chain • Chain breaker • Tire bead breaker • Tire mounting/removal tool • Spare clutch components and hardware • Sprocket guards • Additional LO206/Briggs hardware and fittings
Everything was purchased new and the kart has seen only about 1.5 total hours of driving.
No crashes. No bent chassis. No years of abuse. This was built as a proper kart package and only ran til break-in period.
Complete package — kart, LO206, clutch, gearing, tires, wheels, accessories, tools and stand.
This is a great option for someone who wants to get into karting without having to buy a rolling chassis and then spend another several thousand dollars figuring out everything else.
Selling because I simply don't use it enough to justify keeping it.
$5,750 OBO.
