2013+ geometry opinions

For those that have or have ridden or raced the 2013+ on the track, I'm curious on opinions of the bike's handling traits.

I am putting together a 2013 675R race bike for next season, and can't help but notice the steep front geometry numbers: 23 deg rake and a mere 87.9mm trail. I'm sure you can slide the forks down 5mm or so for a tiny bit more, but it is still pretty steep.

What are your experiences with riding this bike? How is it's stability? Is there anywhere on track at pace that it is twitchy or nervous? I know Rider's Discount runs the Attack Triples on their race bike for Danny...

Good call buddy.. The front is way to stiff on the 13-14.. There are a multitude of aftermarket triple clamps to help offset this trail/rake.. I am waiting for my Evol Technology one (couple weeks away, Steve Korol is from Boise Idaho so I am LUCKY. Nothing is in Idaho.)

Also, the forks construction are super stiff for the bike itself.. I would like a Nitron, Lenny Albin has a alot of experience tuning the 675 and knows the details on all the weak spots.

Dude, what is a bigger issue with the New Daytonas, is the Clutch and Tranny... The Shifting of the 2013+ daytona is the achilles heel of the D675R.. I have had to refresh my 'shifter mechanism' parts 3 times already this season. The pros referesh the poorly designed 'pivot shift plate' in between every racing round.. The bike is strong and untapped as far as power potential.. Its just that the newer bikes are stiff and cant shift worth shit.

All of this coupled with the fact that you cannot get parts without a 30-45 back order from the UK factory.. <<< not a fun thing to deal with from the factory as a racer who nom noms thru oem parts..

Ahhhh.. ive owned/tracked the R6,600RR, and 675R... The triumph, even for being a new bike, has had the most troubles in getting 'race ready'... lots of lil bugs that i feel like there is lil factory support on.. Again, its a UK company, not a Jap powerhouse sooo apples and oranges really..

I have been racing the 2013 for the past few rounds.

My bike is equipped with Attack 28mm offset triples, an RSR rear link, gas Ohlins carts, a modded TTX with a hydraulic adjuster...

What I have found is that the front end feel is great on the brakes even to max travel. The bike seems less precise turning in then my 2006 with similar mods which has caused me to ride the bike differently.. I'm still trying to get the bike fully sorted with the help of Thermosman.....he did all the mod work.

I have not had the shifting issues as both of the engines I have received a modded shift fork. I'm also running an aftermarket slipper(STM) and a translogic shift box attached to the stock QS solenoid.

I highly suggestt investing in a set of kit springs for the valves...

The Translogic box is from a Kawi, you just leave one of the coil connections off. Simply connect the stock QS wires to it and you're good to go!

Nice.. :.) can you control the QuickShift Timings? im sure you can, this thing says it "adapts" to your riding style? idk how that would work but sound steezy

I believe you can hook it up to a laptop and tune it accordingly. I have left mine as it was when it was installed, it works great!

Thanks for the feedback guys.

Had the bike out at two different tracks this past week. First time on the bike really and was using these 2 days mostly for setup. Here's what I felt.

Started with 41mm sag in front and 34mm in rear, and default hydraulic settings per manual. This setup felt "nose-heavy" with the front end feeling like it wanted to push on long fast sweepers. This is on new DOT Supercorsas SC2 front/rear. 33/26 hot as recommended by Pirelli and my local tire guy.

I also have a '13 Street Triple R that feels super stable in comparison.

First thing I did was changed sag to 34mm front and rear, and slid the forks down one line, so 3 lines (2 bands) showing on the Ohlins. This definitely helped, but I can't help but think the bike still doesn't feel as planted as the STR. It wasn't doing anything weird, no issues on transitions, or wallowing, but can't help that it still feels nose-heavy. I don't want to run out and get the Attack triples before exploring options and seeing if I can find a good setup.

Any advice/observations?

There is loads on the Forum on this subject. I raced an 07 and struggled with the front for years. The attack triple clamps are good but also adds a lot more variables to the equation. I gave up in the end and bought an ex World Supersport R6, in my opinion the R6 handles better.

Was there anything in particular that made you give up? The RD bikes seem to be doing well with the Attack triples... In comparison my STR with 96mm of trail seems to feel much better.
