after 2 months on my first bike GPX250 i finally came off. i was going around a roundabout (all the way around) and basically lost the right side of the bike from under me. the bike skidded into the curb and i grazed my knee pretty bad, but other than that im fine. the bikes got some cosmetic damage on the right fairings, throttle, both brake levers, and exhaust. i was pretty flustered when it all happened but luckily a really nice bloke who said he rides a cbr600rr was walking past when it happened and helped me out. im not sure if theres any internal damage (i managed to ride the bike back home, depsite being in a fair bit of pain and really pissed off with myself), so i was jsut wondering if theres anything i should check for? also the bike took pretty long to start up once i got it back up. is this coz the oil had to move from the sides of the bike back down to the bottom? how do i check if theres any oil leaks etc? could i get any problems with the oil in the future? coz even when the bike started, i kept it in neutral for a while with the engine on and the bike nearly died on me again, had to give it some throttle to keep it running. and finally, wat can i do to prevent this happening again? i realised i was leant over way too far, but it all happened so fast i never actually realised how far i leant until it was too late. i thought the lean angle was alright most of the way through the roundaboat, then just as i was close to exiting, i toppled over. how can i get a sense of how far is too far? i never actually braked at all throughout the roundabout, but i think i might have eased off the throttle a bit, is that what could have caused it? i feel pretty relieved theres not too much damage (i basically only need to get the rear brake pedal bent back into position) and im ok. and this def wont stop me from riding in the future, but i do want to avoid this ever happening again to me.
