Hey Chelder. Bike looks great, neighbour.
I'm also putting on a Yamalink. I've talked to Dan at YL and he said the link off the traded YZ250FX '15 will work fine on the WR450F '16, only a mm or two difference. He said to set the the rider sag carefully and I'd be sweet. Concensus seems to be around 118mm rider sag. Seems a lot but I'm not arguing with the experts.
Are you planning on fitting a new shock spring? Lowering links reduce the effective spring rate by around 15% so a 15% stiffer spring is needed to bring the rear end back to an effective OEM spring rate. I'm fitting a 5% stiffer spring with my YL to give me 10% softer shock spring rate. I have a Factory Connection Spring ready to go on. I plan on fitting 10% softer fork springs to balance the whole bike. Also fitting softer secondary chamber springs to add a further level of plushness. I'm a starving-chicken 75kg so respringing essential. All reviews suggest that the bike is setup for an 85kg rider, not the usual Yamaha 75kg Rider.
I see a yellow 60th Anniversary bike in your pics. Not tempted? My dealer is bringing in both yellow and blue and I get to choose. Heading towards the blue. I've got a blue Ti FMF arriving so might look a little 'bright' on the yellow bike.
Hey Gaz, I'm running the Kroozetune 30mm link I haven't used it yet plan on running it Wednesday and Thursday like you I am only a lightweight 73kgs I fi d the shock a bit stiff if my YZF is anything to go off I believe it has the same stock Spring rate so hopefully keep the link will sort it just nice, 118mm of race sag seems excessive I will start out at about 108mm and work from there.
The fork rate will hopefully stay the same I like my forks a bit stiffer generally I do about 10-15 hours on stock suspension before sending it off to a tuner so once I put a few hours on it I'll let you know how it goes.
I'm not a big fan of the yellow at all sorry blue only for me haha!
