I have a brand new 30mm Italkart (tag senior), no time yet to test. I am experiencing a pretty bad hop though one corner only, it’s a fast slightly banked 180° hairpin. Rest of the track it is handling very well. Nutural setting on the front w/ KF hand front brakes. rear track @ 55″ medium hubs @ meduim axle, rear bar is out. My question is wether I should approach this corner first with a setup change, or change my driving. If driving, any advice approaching a high grip & fast 180° would really help. Thanks in advance
If it’s one corner, it’s probably driving-related.
To eliminate hopping, slow your hands down. Do what we constantly refer to as “driving under the rubber”. By that I mean, aim for the same apex you are now, but turn in sooner and more slowly. This will load the kart more progressively and eliminate harsh reactions from the chassis.
Hopping is from the inside rear bouncing up and down in the corner when you exceed the grip limit of the outside tire and start to get slip.
Applying throttle can help plant the outside wheel harder and keep the inside rear up or it can induce a bit of powerslide, smoothing out the hopping. Hitting the brakes usually sets the inside rear down and bogs the kart off the corner.
Driving a kart through a corner relies on you putting in the correct amount of steering, throttle, and braking inputs to keep the inside off the ground smoothly. Smooth inputs = smooth kart reaction.
