Suzuki GSX-R 600 K4
I have spent many years dealing with various M/Bike guru's but I have never been happier than when I randomly found Teut online and had my initial chat with him.
Teut was simply epic to deal with on all accounts, his understanding, knowledge and communication were what I had craved for! Teut listened to what I had to say, recommended a set up and was clear and precise in delivering this information so I could digest it in complete confidence... next thing I had bought a new Nitron Track shock and decided to have the Race Tech Gold Valve front fork tune and off my bike went to Preston all the way from Edinburgh.!This was done via a courier Teut knew of and it was very reasonably priced. 
Whilst the bike was at Teut's he  also handled the Swing arm removal and powder coating, Brembo brake upgrade,  fit new discs, pads, R1 caliper upgrade and  Brembo master cylinder. 
Once the work was completed I went to collect my bike and the day after went on a bike trip to Orkney.  Wow!!...simply  wow! My confidence has moved on and the feedback is fantastic.  Teut has kept in touch to make sure im happy with the set up and overtime we will make some adjustments as I experiment with whats on offer.  Its worth noting that suspension work is vitally important for bikes so doing an upgrade is a no brainer to me. Combined with the service I received its why my other bikes and any future bikes are going direct to Teut.  

Cheers,  Mr.Z,
Edinburgh.
