sorry for the long winded post
Personally speaking from my own horrible experience steer well clear of atomiks. I have had one of these Reign 150's for 8 weeks now and have only had the thing running for 20 minutes tops. Ive had problems since day 1, when i rode it out bush and it just died on me, and had me stuck in the bush for 2 hours at the bottom of a steep hill, the engine will kick over but will not stay running.
I have tried contacting atomik about it via their "Fault Form" on the net. First time took 3 week to contact me, (i tried calling but just got put on hold 3 times for 45 minutes before i gave up) when i finnaly got into contact via email they said to take into an atomik workshop, which i did. This workshop had it two weeks (i gave them ample time didn't want to hassel them too much) and when i went to check whether they'd had it running they said they were "too busy to look at it yet". So i got pissed off, they said they'd look at it later that day. They managed to get it running, so i took it home. Got it home and i couldn't get it running again. So i took it back, same thing "too busy to look at it".... fukin bullshitt i say....
I am now just gonna swap my old motor into my new bike as i am over trying to get anything from these hopeless people. They say they offer full support, warrantee and all this crap when all they wanna do is sell more bikes and not look after you once you have left the shop. If i was in their shoes id want to get a perviously sold bike running as this is how you get return customers....
I have always been a PitPro person, i have bought and assembled three pitpro's now for my mates and we love em, never had one problem with them EVER! And we ride everyweekend and ride pretty hard.
Reason i bought an atomik is pitpro didnt have a 150 available when i wanted a new bike so i thought i'd try an atomik again after my first bike (an atomik) fell to bits after 4 months riding. Never again... Never ever again.... Screw Atomiks, they are shit.....
