I have had my R7 on track twice now and it has all the good bits installed except for my rear shock. The new linkage is coming this week and I can finally get that installed. My problem with this bike is I can not get it to turn. It always seems to want to run wide. Have any of you installed new triples or has anyone encountered this. Maybe with the stock rear shock and a well sorted front end the rear might be to low. Any thoughts on how to get this to turn better and not run wide. Thanks

...if it goes wide, first check the hight at the rear and even increase it if possible. Also reduce rebound damping if necessary.

If you are not oversized and do not race like Vale, the stock shock might work so far.

I have a new rear K tech shock but am waiting on the new rear shock linkage and once it is installed I can really focus on the geometry. I think your correct on the rear ride height.

The stock triples don't generate enough trail at the ground, which is why all the competitive MA Twins Cup R7 bikes use after-market triples with far less fork offset. Look for triples with 26mm of offset, and 2mm of adjustment either way if you really want to nail your setup. Failure to finish the corner is not due to a too low rear ride height, compared to the front; quite to the contrary. The bike will finish corners better with higher front and rear ride heights than stock. The best MA R7 bkes have longer than stock forks. The new rear linkage, if its like the linkage from Robem, with the proper length shock will get the rear ride height close. A better shock will improve grip, once adjusted correctly for you and the track, but the length plus the linkage determining rear ride height is what matters to finishing a corner. If your initial turn in is slow, I'd ask are you trail-braking to, or nearly to, the apex? That is what the bike "wants" you to do to facilitate turn in.

I can get mine to turn easily, this bike is known for being extremely easy to flick into corners. You might be doing something wrong tbh....
GnarDoggs I have been racing motorcycles longer than you have been on this earth and while I'm sure you can get your tricked out R7 to turn in the McDonalds parking lot I was looking for a more educated response tbh.

Yeah Lenny Albin from Ktech does my suspension and he said the same thing that this bike will benefit greatly with new triples and he say 26mm of offset as well. Yes I do believe I am trail braking in some of the corners that this is happening in. I am used to racing my 2017 R1 and need to learn to carry more corner speed. My Robem linkage should be here this week and once I get rid of the stock shock we'll see how that changes things.

Yeah
Really
You might be one of those numptys that never check
Although I hope not
I am always checking pressures, suspension settings and other things, This bike was bought in March and torn down and built up as a racebike as new pieces came in for it. I finally rode it for the first time in late July. I have been racing a 2017 R1 now for 5 years and thought it would be a great bike. I love it so far but have only put about 80 miles on it. I have to learn to ride this bike different than my R1 which I absolutely love and is so well sorted it is a dream to ride. I'm sure the R7 will get sorted out but I'm just trying to learn what others have done as this bike has it issues. Here is a picture of my Yamaha R bikes

Get the link but I’m still running stock clamps about to extend the forks internally to try and help the bike on direction changes and change the valving in the rear shock. It’s wrong too been shredding tire cause of it

Brake calipers are cool 🤟

Check tire pressure
A little off topic but we went racing with an old bike in the vintage class and the owner wanted to try out his new digital pressure gauge. He set the front at 29 psi and the bike went out for a few practice laps. Before the the bike went out again, I checked pressure and it was 62 psi. Didn't take long to realize he read the digital readout upside down. Still can't figure out how he didn't notice the other digits were upside down unless the guage originally displayed 52 (25 upside down) and he happened to add exactly 10 psi when he thought he only added 4.
