what kind of corners?
two threads down "tight turns" you can read some of my brainstorming
what worked for me was a slow bike
yes I am dead serious, my XR250 tought me how to ride fast
she forced me to keep up momentum because I could not accelerate as hard as my competitors
to keep up momentum you have to carry more speed thu the turn to do so you must ride "round", use other lines than you would on a more powerful bike
what do you mean you can not afford a 2nd bike? we are talking about a trashy, vintage XL250, XR200 ... whatever at home I'd look for an MTX80 or DT80, they sell for 50$ the most
one thing I still "practice" a lot, when riding trails with someone slower, is to simply NOT CLUTCH or BRAKE,
throttle action and shifting only feels odd at first, you will go slower on straights and take turns faster than you want to, take different lines than you normally would ... fell somewhat out of controll/insecure at first, but the longer you ride like this, the more natural it feels, the more relaxed you will ride, the more little obsticles you will learn to use as traction, roots, ruts, banks will become your 'friends' not something to kick you off course
