One of my friend owned apache bike. After few months there are lot of sounds coming out and it seems that bolts are loose. Bike needs service always. If you increase accelerator and want to do stunts than there is more possibility that your tyres may slips because in my opinion apache rtr series bike tyres are damage totally because of heavy weight of upper side of the bike and thin structure of tyres. Beside this everything is ok. Gear system and break are awesome.
There are nothing best than drift with this bike but befire you should change tyres. If want to take bike and use it for 4-5 years than my advice is not to buy this bike.
