How I made my Yamaha FJR1300 corner easier

Whilst many people overseas seem ok with the way their Yamaha FJR300 corners, riding on tight narrow roads here and being used to lighter bikes I wanted to quicken the steering if possible. My motorcycle is 2014 FJR1300A and coming from standard lighter bike prior it always feels like it understeers needing additional bar input (counter steer) to hold a line or initiate turn it needed much more leverage on the bars than I have experienced on other motorcycles.

The fanatical self pro claimed experts on the owner forums insist this big motorcycle steers light as a feather. Simply inflate the tyres a few more PSI and it turns like a 125cc one senior member told me and when I questioned that I was flamed by all and sundry whom I doubt have ever ridden any other motorcycles to know better. I am not braking in corners and the tyres have even wear, it’s simply a long and heavy bike with a huge fuel load which is set up with slow steering. There is a partial solution – but it’s nothing being suggested on owners forums.

Before I get to what has provided the best change to the way my FJR steers I want to explain the journey I took. First of all I sought assistance from those owners forums but found them misleading. Besides the few extra PSI makes the 296kg disappear claims the majority of advice was fit a certain model tyre, this varied but most suggested Pilot Road 4 which I found steered slower than the factory recommended Bridgestone BT023GT so I set off to try a few things myself.

The first thing I tried was to set the rear suspension preload to firm.This slightly raises the rear ride height or reduces the sag and thus slightly sharpens the steering angle. This made a small but noticeable difference to turn in speed but at the sacrifice of ride comfort when riding solo. However once accustomed to the difference I was not able to go back so the motorcycle has remained in this setting. You can easy try this on the A series by flicking the lever and on the ES from the dash control.

Building from here and after trying various suspension settings on the front I found the best result was setting the front pre load to soft or increased sag in the ride height which of course opposite to the rear firm preload will slightly lower the front thus further sharpen the steering. Very minor affect, not as noticeable as the rear preload but again so easy to do. 

Inspired by this slight improvement from tiny change in ride heights I raised the fork legs in the triple clamps about 25 mm to lower the front and further alter/sharpen up the steering angle. You can do this fairly easy on the FJR by loosening the bolts at the mid and upper fork leg clamps and then sliding the fork leg up gently. This then made a further improvement which is most noticeable when the fuel load dropped from full to 2/3 or less and the motorcycle was operating without such a high COG. The steering at this point with the combination of things done was a noticeable improvement from standard. No adverse affects. Still ample ground clearance. Not unstable as owners forums were warning like the robot in Lost in Space, actually it still displays understeer and remains slow to change direction but an improvement over stock for zero $ outlay.

The next thing I looked at was ergonomics. The bars on the FJR1300 are a bit low, slightly too far forward and little narrow when compared to a standard motorcycle or other large touring motorcycles. That’s how I find them despite being 6’ tall. I installed a bar raising plate and this moved the bars up 25mm and back 40mm bringing them to a position that is closer to natural. Raising the bars provided more leverage which helped a lot. It also made the FJR comfortable like a touring motorcycle should be.

Along the way I had been trying different tyres. The FJR came with Metzeler Z8 tyres to begin with, these wore unevenly on the front getting scalloped badly. Pirelli Angel GT made the steering lighter but they are soft and the heavy FJR tore the sides away on the front tyre in just one tour then the steering slowed dramatically with the triangle shaped front tread and the rear tyre was bald by just 6000km. The Michelin Pilot Road 4s were slowest steering and the front was premature failure of the carcass about 3000km where they were already half worn out so I just got rid of both tyres. Second failure with Pilot tyres which I will never fit again. The Bridgestone BT-023 GT steers not a fast as the Angel GT but it wears evenly and lasts 10,000km which is minimum distance I find acceptable to last me a riding season and not need tyres mid tour which is a huge hassle in Japan. I’d like to try the Dunlop Roadsmart III but I have never had a Dunlop tyre that didn’t steer slow and wear out fast so am hesitant change from the BT023GT until I can find someone honest to tell me what they are like. All tyre reviews seem to say somewhere “only just fitted” which makes the review null and void , all tyre feel fantastic first couple of thousand km.

Lastly I decided I would change the rear suspension links called the dog bones to raise the rear ride height and further sharpen the steering angle. I had left this to last since it seemed the hardest but in fact it can be done in probably 30 minutes. I chose to fit 30mm raise links which is achieved by a very minor change in the links. I sourced them for about $39 from a eBay retailer in Germany with good customer feedback. Well the transformation this brought once fitted was the most of anything so far (but please note it was in conjunction with the other things already). The FJR straight way felt noticeably lighter to turn. Ok you still are riding a heavy tourer but it honestly felt somewhat easy for the first time ever and actually became fun to ride on tighter corners not needing me to drag it around every bend. It will hold a chosen line easier now and does not want to understeer. It is still a big heavy bike which you need be aware of but now it steers well even in very tight corners.

The best way IMO to install the dog bone links is to put the bike on the centre stand and loosen the dog bone links then use a jack to lighten the rear wheel from the link pins (not supporting the bike which is on stand - just the wheel weight) take the top pin out then remove the shock lower mount pin and rotate the lower link pin forward past stand then remove the dog bone links. For install reverse and use the jack to position the wheel at correct height to get top pin back in with new length links. I took loads of time and it still was all over in 40 minutes.

To anyone seeking to make their FJR1300 turn better I would say this is really a core item of the suite of things I did that now combine to make the bike turn much faster in conjunction with using the BT-023GT tyres that don’t lose their contact area radius shape as much as the others which is another factor that slows the FJR’s steering.

My long term Yamaha FJR1300 review is here if you would like further information.

  1. Great stuff mate on working out how to make the bike handle. Should sell it to Yamaha now as they obviously don't know. Haha

    1. Ha-ha, I wish! The machine is built primarily for the US market so I presume the slow steering is by design. Not sure why. Hope this helps a few people as not much in the way of genuine info for people who like it's comfort but still want to enjoy a corner.

  2. after many years (and a couple of FJR's) I found MY solution to the problem. I switched to DUNLOP ROADSMART III... what a difference they make.

  3. Good article! Thank you for telling it like it is and the tip about lowering the front end. I too raised the rear and it was a BIG improvement.
    I didn't know how much to lower the front and your articles guidance is helpful. I have an Angel GT front/Dunlop RoadsmartII tire combination, its the best of the many that have been on the bike in 50K miles.

    1. How many miles/km do you get from that tyre combo? And which is on on front and rear? I am at 50,000km now using BT-023GT last two sets.

Hey go right ahead and post something here. I'd love to hear from you and your comments will be published soon as I review them - this is just to stop spam otherwise I end up with 50 'cheap viagra' advertisements posted here.
