I have ridden my MT-07 just over 6000 miles in the past 12 months, all of which has been for fun and pleasure. The bike has covered a total of 9100 miles. I am not suffering from any corrosion luckily, but I live inland and rarely go out in the wet. All previous comments are valid and appropriate. The engine is terrific, brakes are average, horn/switch is diabolical, suspension is a compromise. Even my Maxtons cannot cope with washboard surfaces, the inability to smooth out this type of road irregularity is unlike any other bike I have owned. On decent tarmac roads the Maxtons are great. I have a 'comfort' seat and the original standard seat but neither is particularly comfortable after a couple of hours. The 'comfort' seat is actually firmer than the standard seat.
The engine always starts on the button and is temperament-free. Stalling is vanquished to history now that Seton Tuning have re-mapped the ECU. The torque and power bands are also significantly better. I used to get 68 to 72mpg on a careful poodling ride and around 60 when driving fast. This has dropped by about 3mpg since the re-flash, but the performance is far better.
The speedo location is totally useless, totally obscured unless you wear an open-face helmet. I moved mine some time ago.
I have not had any mechanical or electrical issues at all so far, although I might remove the clutch and do what "sdrio" did some time ago, purely as precaution.
The MT-07 fulfils it's design brief. It is fantastic value for money and offers excellent performance. The quality of components is inevitably tempered by the overall price but so far mine still looks good. ACF50 and Muck-off silicone spray on the fork stanchions must be helping.
My rear tyre is just below it's 1mm legal tread limit in the centre. In truth, I could probably get more miles out of it yet, but am changing it next week for a Michelin PR4 170/60/17. I am hoping to improve handling, nimbleness and reduce the rear-end wandering tendency, whilst riding over tar-banding and poor longitudinal road repairs. I have always felt that the 180 rear tyre is too fat. I will report back honestly concerning the 170 in due course.
My MT-07 does everything that I need. It is fast and punchy, feels safe and confidence-inspiring and I enjoy every ride. Ok, my bike has had a lot of money spent on it by GAZ2212 and some by me, to make it into a better bike. I specifically did not want a heavy bike. 170kg is about as much as I can manage these days. For lightness and ease of man-handling I still prefer the uncannily smooth new KTM 690 Duke, although I doubt that it would be as reliable as the Yamaha. I would still have to spend money on it to lower the suspension and do a few other things - and it's a pricey bike to start with! If I had the space and money I would have one as well as the MT. My days of riding big fast heavy-weight tourers are over. The MT-07 ticks most of my boxes. Reliability has been superb.
