I bought the bike for $500 off some guy on gumtree with a flat back tyre. So I fixed that and took it for a burn. It's so fast. And the acceleration is insane. Have had no problems (although I haven't had it for long). It's really fun to ride and has a lot of acceleration. The grips are comfy and so is the riding position (I'm not that tall) and the seat is comfy aswell. The suspension is nice and soft and the tyres have really good grip. The clutch is smooth and good to learn on. The bike starts first kick almost everytime if not first it'll start second I will ad to the review as I experience problems or encounter other things and after more thrashing and jumps and stuff Engine: Its an oil cooled 140cc Atomik YX engine. It has plenty of power, its kick start only which doesn't bother me because starts first kick almost every time. It's running a MOLKT carby which seems to do the job just fine. Also the guy I bought it off replaced the stock air filter with a UNI filter. And it has a it has a 32mm race pipe with a pro circuit style muffler and its nice and LOUD 8/10 Suspension: It has alloy USD's which feel nice and smooth and absorb the bumps nicely. It has a 1000lb nitrogen charged gas rear shock with adjustable preload which also absorbs the bumps really well and makes for a comfortable ride. I haven't jumped it very much yet but they both seem to hold up fine. 6/10 Tyres and brakes. The tyres have good tread with good grip on concrete and grass and dirt aswell. Seem to be good thick rubber as it was a prick to change the tube. The brake are single cylinder hydraulic breaks which pull the bike up quickly and are very smooth to apply (they don't lock up when u don't want them to) 5/10 Frame: As I said earlier it hasn't had much thrashing at all but its a SDG trellis chromoly frame with a cradle which is as far as I know quite strong 9/10 Overall bike I'd say is a 8/10. Very nice bike. I recommend it.
