    My DN-01 is a 2010 model with 18200~ miles on the odometer. 99% of the time I'm a fair weather rider and the bike has been kept (in my ownership at least) inside a dry garage. I do not use a pressure washer to clean it.

    That said, the day before any of the failures, we were caught in a heavy rainstorm on the motorway. We rode in it for about 15-20 minutes and then pulled into the nearest services and had a coffee until the weather passed.

    The first day of failures, the bike got stuck in third gear not long after being started whilst riding through the Lake District (for the non-brits; a picturesque area of England with lots of hills and twisting roads). I tried to clear this by stopping and starting the bike (big mistake), the bike then got stuck in first.

    We limped to a nearby parking spot where I pulled the fault codes and checked the sensors, I assumed it was just moisture and sprayed the connectors on the right side of the engine out with WD40. After a couple of attempts, I managed to get the bike working again for a short time. A few miles down the road it got stuck in third gear again.

    Limped it to another parking spot, cleared the fault codes again, tracked the actual fault code to the swash plate angle sensor under the bike, sprayed that out with WD40 and rode on again. Bike working fine until the end of the day.

    The next day, the bike changed gears fine until it warmed up, again getting stuck in first (right before the slip road for a motorway, eek). Limped it back to a petrol forecourt, pulled off the swash angle sensor, checked it with a multimeter (all fine), reattached it. Phoned my local Honda garage who suggested removing the swash plate angle motor, but I couldn't get the fairing off so I called out the AA to get it recovered home. That took 9 hours.

    Honda quoted me 645 to replace the motor (including 1 hour labour). It's not a cheap part.

    If I was to guess why it disintegrated? Old age coupled with hot-cold cycles and possibly hot engine plus cold rain pushed it over the edge. I think the broken magnet bits were at such an angle they would permit the motor to spin one way (change down gears) but not the other way to change up gears.

    I'll be getting some photos as soon as I get my bike back in a couple of days.

    That IS expensive to replace/repair ...first I've heard that happening. Any input from Honda as whether that is a common problem? I know that they have A LOT of DN-01 running around in Japan, so i'm just curious. I might CONSIDER selling or trading mine in BEFORE that part fails ... even though I don't want to! PLEASE keep us posted!

    It's not a cheap repair I admit, but it's not a complete gearbox failure (that would be the end of the bike to me, far beyond economical repair).

    I'm secretly hoping that once I get my bike and the damaged motor back I can check the part number and see if there are cheaper alternatives. If this part is to be a weak point, best we be prepared, right?

    Thanks for the comprehensive reply. Hopefully not a common failure but unacceptable at that mileage and typically overpriced compared to a similar car part. Had a long day being relayed by the AA on three vehicles from Liverpool to London years ago, after a week at the TT. Honda aren't doing too well there either this week!

    Got my bike back, working fine again.

    As promised here are the photos of the motor...

    Oh and the part code for said motor is: 31300-MEH-003

    Quick Google suggests it can be found cheaper online however the cheapest price seems to be $250 / 195 from the states

    I'm interested to find out WHY Honda charged SO MUCH for the part and labor!
    645 equates to something like $834 and the part: 31300-MEH-003 IS a Honda part. Talk about price gauging!

    The labour was 1 hour at 50+VAT (or 60 with VAT) which is quite reasonable. It's the part itself that's jaw-droppingly expensive..

    At least none of the 14000 viewers are reporting the same problem. Apparently rare earth magnets oxidise to disintegration but probably not relevent here.

    HI everyone. I'm a brand new owner of DN-01 and also (unfortunately) the owner of new PROBLEM. From time to time I can't start the engine - Key turned on. Ignition registering that bike was in gear, or at least not in neutral, the "-" flashes to indicate a failure (4 slow, 5 faster).
    I was lucky finding this forum which gave me some idea where is the problem.
    I've found also some helpful info on this website:
    http://www.fireblades.org/forums/gen...trouble-2.html
    Please see the last message.
    I have a few questions and I will be grateful if you can help me:
    * is there any chance to get Service Manual in pdf as I presume it should contain fault codes so I could read what flashing icon "-" says
    * does anyone know what the swash plate angle sensor is responsible for?
    * during my travel from UK to Ireland (500 km) I've experienced also a few yanks when reducing speed (55-50 miles/h), this could be from HFT when shifting down, does anyone know what it can be?
    Looking forward for any answers and suggestions. Thanks in advance! /Greg

    Hi Greg,

    Sorry to hear you're having problems, the HFT system is great until it starts to have issues, then it's pain. The issues you are describing are very similar to my own.

    Firstly, here is a link to the service manual (150 meg!). You will find the HFT section starting on page 277 / section 11.

    The fault code you have mentioned (4 long, 5 short) is (edited) DTC 45-1 - Neutral oil pressure switch circuit malfunction.

    The swash plate angle sensor is (in effect) the gear position sensor. It's a 3 pin variable resistor that is located at the bottom rear of the gearbox behind the reserve water bottle. The sensor is held in by 2x Allen key / Hex bolts (I think either 6 or 8 MM).

    Comparing my issue to yours, I could always start my bike and go into drive but unable to change from 1st gear; the magnet broke apart inside the electrical motor that operates the swash plate (gear position), jamming it. This could also explain your harsh gear changes. How are the gear shifts in tiptronic / manual mode?

    I think you might have 2 separate issues here;

    1. I think perhaps your swash plate angle sensor (or worse, the motor) has failed. This in itself does not prevent you from starting the bike or engaging drive / neutral.
    2. There has to be an issue elsewhere to prevent it starting, possibly another fault code after the 25?
    The only HFT issues that blocks / prevents the bike from starting are DTC 14-1 (Neutral / Drive solenoid lock) and DTC 45-1 (Neutral oil pressure switch malfunction). Unless you've let the oil get too low, this is unlikely.

    There could be other issues like moisture in the kill switch?
