I like the look of the Race replacement that's coming as you will be able to recharge it yourself. The new Dainese system also lets you do this.

PSi are only one hour from me, which is handy, although 4SR are only ten minutes from me now they've opened their new store, so I might give them a go for my next suit.

To keep my post somewhat relevant, I've not tried Vireos (although I have heard of them).
 
Couple of my group are wearing the 4SR stuff .. not so convinced one had MTM and it was miles off…

I went MTM RST measured at their uk hq
Love the fit .. didn’t realise how long I had been fighting a off the shelf Dainese one in pain..

So surely at the first fitting he would have said it’s no good and they would have adjusted it to make sure it fits correctly? That sort of thing can happen and would be sorted out.

Sounds familiar… Surprised you didn’t tell your “friend” to suck it up, pick up some scissors and thread, and sort it out himself.

slightly different to sticking a drill in a hole for 2 seconds....

although he did complain, refuse to send them back, demand a refund, and then used them!
 
Overall REALLY happy with this.

I can move in it WAYbetter than my cowhide Dianese and it’s not even broke in yet. Has much better hip protection built in than the Dianese so I understand why they pushed me away from the Tech-Air 10.

Has lots of little touches that my Dianese doesn’t have…like these built in grip pads in the inside of the knee and leg for gripping the tank, sat on the bike with them and they work so well that you don’t even need tank grips with them.

Overall the suit fits perfectly, except for two key areas, the distance from knee to ankle is off a bit, and from elbow to wrist. They barely connect with the Velcro on my D1 boots, and my gloves barely cover the sleeve bottoms. It’s functional but the next suit I order from them I will add 3 centimeters to those two measurements.

My PSI fits great. But makes me look fat :(

Looking good :)

Not sure if you did so, but when taking the next set of measurements, make sure that you are sitting on the bike with a suit and measure again

I guess if you were buying from a US supplier you'd want it to fit better on the leg and arm length but it's a bit of a pain to send it all the way back, unless that was down to the measurements taken.

When I had my suit done the fitting included taking measurements when sat on a bike (a lovely old 500 2-stroke Sheene replica) and the fit was perfect first time.

The off-the-shelf suits from PSi had the grip material on the thighs like yours had but for some reason they don't put it on the custom suits. It seems like a good idea though.

The suit looks good. 👍All you need to do now is crash in it so you can report on how well it stands up to some abuse. No rush...🤣
 
Guess where this WON’T be muahaha….Back in the shop lol

No modifications needed lol

Well, two actually, Zero Gravity is making a short run of taller windscreens for the bike, and the one bit of design flaw that I’ve found on the bike is that the right heel rests right on the exhaust holder bracket, so I’ll probably need to fab a bracket to drop that exhaust down an inch.

So the V4 25 Anniversario 916 is back looking mostly OEM, unless you look closely lol

Still has all the MotoCorse stuff, the suspension stuff, the exhaust, and the H20 Radiator.

I forgot how much I like the Foggy livery, gorgeous bike…I might just keep it as my street bike for when I want to go for a quick romp between track days.

The KTM RC 8C is living up to expectations…so fun. I’ve had it at Chuckwallah for an easy break in day, and last weekend at Big Willow.

Big Willow is really a track set up for liter bikes…very long straights and huge sweepers like Phillip Island…even so I was about 2 seconds faster than on my V4.

The bike has sooo much feedback, and is soooo forgiving…so it tells you exactly what mistake you made, but lets you correct it even mid-corner without terrifying you.

Will take several more track days to get use to it. On every single corner after two full track days I find myself saying “I could have waited longer to lift throttle and I can carry way more speed through this corner.”

Not gunna lie, some small part of me misses correcting my bad lines and slower corners by twisting the throttle and being able to close the gaps on the straights with the V4.

But this bike is making me a better rider already, much more focused on, and aware of my line, and markers etc…

It is a blast to ride, it just flows around the track and asks you to take that corner faster than the last time, and tip in at a faster speed, and wait longer to let off throttle coming off of a corner.

Corner exit is where it really shines though…with this bike I’m already well into the meat of the throttle before I even reach the apex, and am accelerating hard almost as soon as I’m done trail braking. You can essentially have the throttle damn near pinned right as you pass the apex, which is a hoot.

Not that the bike needed it, but I did make a few mods 😂😂😂

Mostly because I had the parts in my garage already, and they do not change the fundamental characteristics of the bike.

I put my GP4-MS calipers on there as well as my thumb break, and my Brembo Evo GP 17 brake master cylinder.

The bike is torquey and light so the front end gets light on acceleration and the rear brake is absolutely needed. I’m used to using a handbrake for the rear caliper so that was a no-brainer modification.

With regard to master cylinder, for whatever reason KTM and Kramer use a 19 cylinder piston with those 30 mm piston calipers. I found that the breaking was too abrupt with that set up. The 17 mm master cylinder meets better with those 30 mm caliper pistons, more ability to finesse and feel the brakes. Which is on that bike. You hardly use the brakes except for trail breaking and you trail break every single corner. On many quarters just the engine breaking is enough to get you slow down to the right corner entry speed. so I end up, just dragging the rear a little bit to shift and close down on the Apex without even touching the front brake.

Fun bike, Not as scary and thrilling as the V4, but just as fun in a different way.

Thanks Steven, that's a very good insight into the relative track experiences on the two bikes.
Do you think the better times on the KTM are from improved lines that are more difficult to achieve accurately on the V4, later braking, the better corner exit drive that you mention or all of the above?

I guess I'm asking if you were to go back to the V4 after learning more from the KTM, could you match or better the KTM (on a track that isn't favouring power)?

I'm trying to talk myself out of going down a similar route to you 😀
 
Interesting that you are faster on the KTM.

If engine braking is enough to slow you down to the required speed then it sounds like you can leave it even later coming off the throttle if you use the brakes. That's probably a significant mental adjustment!

I guess the master cylinder is a matter of feel - as discussed elsewhere, Brembo recommend 17mm for those pistons, many use 19mm and KTM and Kramer choose 19mm, while Ducati fit 16mm. 🫣 🤣

Did you notice any difference with the GP4-MS over the stock Stylema or did you put them on immediately simply because you have them. I seem to recall that you have titanium pistons on the MS.

The KTM sounds like a lot of fun and it seems it is achieving what you wanted. I'm not at all jealous... 🤪

It will be interesting to see how the experience translates to the V4R when you eventually get one.

Yeah I was thinking about that specifically, why am I faster already on the KTM and will that carry over to the Ducati.

To the former, yes, it’s better lines, and better drive off the corner earlier in the corner…as I get use to the bike I think my corner entry will be a lot faster on the KTM than I was achieving on the V4.

To the latter, yes I absolutely think I will be faster on the Ducati than the KTM when I go back to the Ducati. But right now, I sorta got to a peak of lap times on the V4 because the bike was so savage and fast that it was kinda keeping me from really focusing on the line and being comfortable with drive off the corner…the bike’s power is a cheat code, and gets in the way of rider development for a guy like me.

On a highly technical track like Streets of Willow I think this bike might always be faster than a V4 in the hands of anyone who’s not a professional rider. Which bares out, because RoadRacerX has gone faster than the official lap record at Streets and he did it on his RC 8C.

So after only two track days, yeah for sure I think this bike will make me faster on the Ducati, it’s impossible to do a fast lap on it unless you get your line right, body position right, braking on entry right, and pull on corner exit right…but the bike is very forgiving when you make a mistake, and encourages you to ‘get it right’ while you feel in complete control of the bike.the RC 8C give ALOT MORE rider feedback than the V4, so you know immediately what you just got right or just got wrong while in session…so the very next lap you are correcting versus on the Ducati sometimes it would take hours or days of self assessment to figure out after the fact exactly what I was doing wrong.

I guess a different way of saying it, is that at least for me on the V4 I felt like (if I go often enough) that my riding improved track day to track day, whereas on the RC 8C I feel myself improving on each lap.

Not much difference between the GP4-MS and the Stylema’s at my riding level at least…pad choice and MC choice seem to make a much bigger difference.

And you are exactly right about. I’m still not carrying enough speed into corner entry on the bike. It’s probably gonna take two or three more track days to get adjusted to this and that regard.

It’s no surprise that you would break way later on the RC 8C versus the V4… but what has been a big surprise is how much later you need to wait before you lift off the throttle… I’m still adjusting to that because it feels like I’m defying the laws of physics to stay in the throttle as long as I know I need on approach to a corner. Basically I just need more laps to get mentally adjusted to it on.
