    I just put the second tank of gas in my XLR125. Was wondering when it was finally going to run out. Took 8l for 270kms i.e. 3l/100km This was 50/50 urban/rural riding so may be a bit higher consumption for all rural riding.

    You smoker fellas might be faster but I'll only have to stop 1/2 as many times (or less if your bikes die)

    Great write up in Kiwirider this month by Racing Dave....stand by for more entrants!



    I think RD is planning on cheating, he's got a new bike for this and should be made to walk at least half the route.

    Honda NXR125ES, apparently a commuter / ag bike which he is frantically modding...bash plate, bar risers etc.

    Clearly almost a works bike and I suspect actually sponsored by Blue Wing Honda. Obviously time for some rules to be "refined".

    Good write up (2 pages even) with the credit to yourself well expressed, you should pat yourself on the back Ryan.

    He's not technecally breaking any rules, BUT it certainly takes some of the spirit out of it. Yes he will probably finish, no I prossibly will not, but will certainly be a challenge trying to get there. Most of the SBC bikes have been $1500 or under, granted the NXR dosen't cost much more brand new.

    Where's the challenge if you know your gunna finish!

    Maybe I'm just jealous. Hey YAMAHA, I could do with a sponser

    All's fair in love and war

    Bought and paid for, as all the modifications have been, by me.

    As it happens, I was down in Otago a week or two ago (biking the Rail Trail) and took the 'CG125 Adventure Special' along to see how it would cope with parts of the course (with Racing Maree pillioning). Low gearing was helpful, as the NXR is not a ball of fire. The decision to not use road-bike suspension is the right way to go, as the terrain will be very unforgiving on anything weak or elderly, and I don't just mean the riders.

    A sub-sub-category for the Dusty Butt of two-up under 125cc would be a significant challenge, but Maree has declined that possibility!

    My better half is still reluctant to give the two dayer a go on the Transalp, let alone getting squished onto the back of a 125 with me for the one dayer.

    So the NXR is on stock gearing? I have gone quite a bit taller than stock (14:53 from memory, though I could be wrong), and last time I spoke to CooneyR he was talking about going even taller. It makes hill climbing a bit sluggish, but means that we won't be reving the t**s off the bikes on the long straights through the Haka etc. I'll be interested to see the 'Adventure Special' NXR.

    Hell. Noone has done the 2-dayer 2-up yet. Let alone the 1-dayer.

    Balrog and MagicFairy tried on the 1st DB but exiting the Rainbow Jim got a bee sting beside his eye and had to give up.

    The NXR125 comes standard with 17/54 gearing, which is far too high for anything but downhill/tailwind riding. Even on the flat, response is sluggish.

    I’ve gone to a 15T sprocket on the front, so now it’s buzzing at 80 km/h, but at least first gear is properly useable off-road, and the gaps between the gears have closed up to the extent that it’ll pull subsequent gears after each change, when riding uphill.

    Two-up, Maree and I climbed the pylon track out of Clyde, towards Bannockburn, which is seriously steep on a little bike, and pretty rough with rocks and ruts, using a mix of 1st and 2nd – mainly first! We both had to lean forward to stop the front lifting. Good fun!

    Finally managed to find a copy of the Mag at Auckland Airport on Sunday evening. Cool write up RD. Only thing is you make us sound like a bunch of complete nutters. Guess that's probably not too far from the truth though!

    There is an irony worth watching. RD (an older gent) on a young buck of a bike and El (a young buck) on a older gent of a bike. Combined age of bike and rider is probably about the same.

    I'm now running 15/53 instead of 13/53. Poor thing was fair humming at 80 with an absolute max of 90. Didn't really like doing even 80 cause it sounded like it was going to pop. Not been on the open road since the 15CS change but hoping that it is a little more relaxed at 80. Its much nicer to ride around town with the 15. I reckon it was under geared with the 13CS.

    It won't be the slipping clutch that stops you on hills now, it'll be the gearing instead. Better do another test ride. Worsleys Rd is close.

    I've replaced the clutch so no slipping any more. By the way I have the castelated nut removal tool for the centrifugal oil filter and it used to be used to remove the clutch on the older XL125S's. People are welcome to borrow it.

    I went up Worselys with the 13CS and found that it would pull first easily and it was a bit rough for 2nd in most places. It would be good to do this and also do some high speed uphill runs as well cause I suspect that is where the biggest difference will be.

    When El finishes his mods to the LT2 and gets it running again we will definitely be doing another run. Maybe a "race pace" run for a couple of hundred kms around Banks Peninsular.

    Cheers R

    Hmm that's interesting on the gearing there Ryan.
    I had an XL100s as my first (road legal) bike.It would pull 90km/h and I'm pretty sure that was at redline.As far as I know,it had stock sized sprockets,but I could be wrong as we're talking 16 years ago here

    Yeah the old girl is going through a fair amount of surgery at the mo. Not a whole lot left of the pretty bits, but a few more practical bits. I've changed my gearing as well. Gone up from a 14T front to 15T with a 51T rear. Should be able to stretch the old limbs a bit more, whilst still being able to climb a hill. Fingers crossed!!

    Once we get back from the pre run I'll get her sorted.

    Cheers

    Stock gearing is 17 51 as far as I can figure. That would give about 110 - if you ever got there! I reckon my XLR has been used as an off road play bike hence the 13 53 gearing.
