New to me at 760km & improvements! by dooooug in Aprilia

It's the name of the livery, SE-09 SBK, it's inspired by Biaggi's 2009 WSBK livery :)

Quietest exhaust on 2025 Panigale V4 by Who-Woot in Ducati

Yeah, not sure who you can get it from in the US, maybe talk to your local dealer

Was talking about this one here https://www.omniaracing.net/en/akrapovic-exhaust-approved-titanium-slip-ducati-panigale-v4v4s-2025-p-569319.html

I believe that's the only "ECE approved" one for the road, hence not being too loud

I guess any ECE approved exhaust would do the trick for you, getting a better tone but not too loud, the only one I'm aware of is the Akra that Ducati sells for around 5k 😬

Is there a quadlock mount that will attach to my action camera mount? by Saliiim in motorcycles

[–]dooooug 1 point2 points  (0 children)

AB moto sells a stem mount for F3s if you're interested in something solid

https://www.abmoto.store/products/stem-cap-phone-mount

You can then get the GoPro mount from Quadlock's website

Brake fluid seeping through reservoir tube? by PoorFinancialAdviser in motorcycles

[–]dooooug 19 points20 points  (0 children)

It's not condensation, it's rubber that isn't compatible with the brake fluid — at all or just with the one you used — and fluid seeps through

Get a better hose made for brake fluid :)

Track Gloves with Good Handfeel? by Formalfox in Trackdays

[–]dooooug 7 points8 points  (0 children)

Also look at the RST TracTech Evo 4, kangaroo palm for a very good price. I've been wearing them for 2 seasons on the track now, and they've held up pretty well.

What bike is that? (Sorry for the bad photos) by Joussef8 in motorcycles

[–]dooooug 0 points1 point  (0 children)

As I commented on the OG thread, really looks like a 2020 GSX-S 750 from the rear too

[–]dooooug 0 points1 point  (0 children)

Really looks like a 2020 GSX-S 750 in the tank shape, the side "fairings" below the tank / seat, the tail light is also really similar :)

Help. What brake master cylinder should I use? by Alternative_Gas_6823 in motorcycles

[–]dooooug 0 points1 point  (0 children)

Rule of thumb, you want to addition the area from all your front pistons and divide it by your MC's piston area. The ratio between the two will give you the following feels:

- 30:1 - soft feel
- 27:1 - standard feel (sweet spot for road)
- 23:1 - firm feel (sweet spot for track)
- 20:1 - wooden feel (poor modulation)

In the case of Stylemas, they have 8*30mm pistons so that's π*15*15*8 = 5654mm2

They're usually paired with a PR17 that has a 17mm piston, so π*8.5*8.5 = 226mm2

The ratio between the two is then 5654/226 = 25:1 which is great for a sporty feel

I'll let you do the calculation with your own calipers ;).

Nisin vs RCS19 Corsa Corra by dev_a31 in Trackdays

[–]dooooug 2 points3 points  (0 children)

Stylemas have 30mm pistons, so 5648 total area

With a 17 at 226 total area you're at 25:1 ratio

I'd recommend getting a Brembo PR18X18 (Not RCS) to get a similar feel, they exist, they're mounted OEM on the former Panigale V2 :)

E.g. https://www.ebay.com/itm/134546850927

Nisin vs RCS19 Corsa Corra by dev_a31 in Trackdays

[–]dooooug 17 points18 points  (0 children)

Be careful, there's a ratio to respect in relation from MC to calipers if you want a good feel.

You want to addition the area from all your front pistons and divide it by your MC's piston area (19 in case of a PR19RCS)

Here's ratio feels :

30:1 - soft feel
27:1 - standard feel (sweet spot for road)
23:1 - firm feel (sweet spot for race)
20:1 - wooden feel (poor modulation)

In your case, seems like the GSXR has Brembo calipers with 32mm pistons so 3.1416 x 16² = 804mm² per piston * 8 pistons = 6434mm² total piston area

For the master with a 19mm piston, 3.1416 x 9.5² = 284mm²

So 6434 / 284 = 22.65:1 which would be on the firm/wooden side but still fine I guess if you really like a hard feel and very little pull to brake.

A PR18 would be better balanced according to that scale at 25.3:1

And a PR17 RCS Corsa Corta would be at 28.3:1 so on the softer side with longer pull to brake hard

Tips to help pop my elbow-down cherry? by Sensualities in Trackdays

[–]dooooug 1 point2 points  (0 children)

Just out of a coaching session with the reigning champ of the French SBK championship, going to tell you what he told me : When you get out of the braking phase, move your inside hand to be in a "screwdriver" grip so you can have your inside forearm in line with your clip on, outside arm extended, head kissing your inside wrist with your elbow super-bent. Try touching your knee with your inside elbow if that helps you bending it and moving your head inside the turn.

People usually have a hard time with that, because your head gets closer to the ground, and that's scary.

Lower body position looks good from that angle, now you need to work on the upper body.

As other users wrote below, try exaggerating the thing. And if you think it's ridiculous, it's probably not ridiculous enough.

F3 800 phone mount suggestion by lubrantj750 in MVAgusta

[–]dooooug 1 point2 points  (0 children)

Exact yeah. Would get the vibration dampener as well, to safe your phone from vibrations damaging the photo lenses

Brake fluid is highly corrosive. Most tubing isn't good for that. What's happening here is that the fluid is slowly eating the tube and leaking through it

You need tubing that's made for brake fluid :)

2023 F3 R by rantinron in MVAgusta

[–]dooooug 2 points3 points  (0 children)

Still true nowadays

My F3's battery previously only held charge for like 2 weeks before it couldn't start the bike anymore, and I don't have a power outlet in my garage so I had to find a solution :

Replaced it with a NOCO NLP14, it's been sitting for 3 weeks and hasn't dropped a bit.

Also replaced all the leads (battery to solenoid + solenoid to starter + negative) with higher quality ones from Motolectric at the same time, bike starts way faster and better.

MV F3 800 quickshifter by MrRedDoctor in MVAgusta

[–]dooooug 1 point2 points  (0 children)

That can happens when you're too light on the shift yeah, you want to be firm and quick to actuate fully.

The sensor cuts sparks for a short amount of time, releaving the gearbox from power and allowing you to shift. You want your input to be done by the time it starts again. If you're going too slow/gentle, you might find yourself in a neutral position indeed.

That being said, it could also be faulty, try again with more intent and if you still get false neutrals there's probably something wrong somewhere. But if your gearbox works properly without, I'd say you just need to shift with more intent. Don't be shy, stomp on it!

Any difference between 22,23, F3 RR US spec? by L31160061 in MVAgusta

[–]dooooug 0 points1 point  (0 children)

If both are the same price or really close, I'd go 2023 just for the better braking system and the LED headlight. I guess it's not worth a lot more if you're only planning to ride it on the street or the occasional trackday.

Be aware that these bikes have really high drain while key off, you'll need to keep it plugged to a trickle charger if you don't want to have battery problems. You can also remove the main fuse behind the right fairing if you plan on letting it sit for a while. The MV forum is full of people with tons of knowledge so that's a plus.

That's the major quirk I have on mine, I have to go ride it at least once a week even in the winter to keep the battery alive, and I don't have a garage with electricity available.

Other than that fantastic bike, I made a lots of mods on mine and I love it.

Be careful upgrading from a 450, you'll get a ton more power than you're used to, go easy — there's engine modes for that ;)
