Silverstone track day on the 899 Panigale

[@Bengeyboy]

Just been reading all the comments, some people think they are Rossi- all about the chicken strips blah blah blah. Did you enjoy it... YES, was it your own bike you wish to go home with at the end of the track day.... YES. Who gives a SH*T, we live in a horrible society of "BIG" Egos and quite frankly small minded people. Keep up the uploads haven't missed one yet Andy

[@hudsonrilke]

cool. What a memory for you. Catching up with your vids as you can see. I came back to biking after 30 years less than 2 years back and watched a lot of your stuff then, I wouldn't have forecast you'd get a Panigale.

[@TheMissendenFlyer]

I like to keep people guessing! ....and welcome back...

[@digitaldogs233]

looks really fun. I think you had your cam in a perfect place too..gave a really good feel..especially to a guy who hasn't rode for abit. I like to watch the lines they take..also like the respect given to a faster rider. I fallow two types of riders..the USA mental heads and the UK information heads. both are fun to watch in there own way. any way injoyed the virtual ride fella. must admit I do love telling the USA guys I follow that with bikes we have real history. But hay it's all out of fun..I'm never disrespectful, it's just a fact. R.S

[@TheMissendenFlyer]

Yeah it was great fun (albeit expensive) - thanks for watching and the positive and encouraging comments as ever - cheers - TMF

[@digitaldogs233]

+TheMissendenFlyer your welcome..I very much injoy your stuff. 👍

[@MiddleagedRider]

Superb video. Thanks for sharing. I did a similar Ducati day on the National circuit a few weeks back and got to ride the 959 and 1299S. Awesome bikes on an awesome track!

[@TheMissendenFlyer]

Thanks Middleaged Rider - I did think about hiring one of their bikes.....what do you normally ride?

[@MiddleagedRider]

+TheMissendenFlyer most days a CBR650F. There's some (crappy - issues with the drift) video of me at Silverstone on my channel. BUT I've just gone and bought myself a new toy last week for weekend fun. Soon to be revealed!

[@DatOldeBiker]

Thanks Mr. Flyer. So it appears you know your way around a track. Good speed and no dicey moments well done sir! Although I wouldn't call myself a Ducati fan per se, the sight of all those Bikes on the grid waiting to start the lap.. Oh Man! :>)

[@TheMissendenFlyer]

Yes cool wasn’t it!

[@TJ8]

Ah! I was the chap who spoke with you about calling a pan on my navex at Oxford! I managed to go out on the final wet lap too so got an extra session in - needless to say it was extra slow! My day also worked out at £6 per min! Fun though. Enjoyed chatting with you.

[@TheMissendenFlyer]

Ah brilliant! Well done for finding this video of the day, I think you feature in it somewhere if you watch closely! ...and yes I didn't fancy binning my bike in the rain so called it a day, but on the basis of the three 20 minute sessions I had working out at approx. £375/hour maybe we should have gone flying somewhere sunny instead!! Good to meet you, enjoyed our chat...now you know where I am do stay in touch! All the best - TMF

[@DarthPeachy]

Absolutely fantastic. Still never doen a track day myself yet, keep missing chances for one reason or another. Hopefully will do Jerez this year, fingers crossed.

[@TheMissendenFlyer]

Yes you must make it happen - it's great fun and I think every biker should try it at least once....and I think it makes you a better rider overall. Thanks for watching....TMF

[@dayriderschat]

I'm glad you enjoyed the experience ... It was interesting to us old English in Australia .... We are still ton up boys, but all with a clean licence ..

[@TheMissendenFlyer]

[@mattmcalister1915]

There's a film that was made to give riders advice on riding. It's called Twist of the Wrist. It has the most appalling acting you've ever seen, the worst plot too, but I've found the advice really useful from it. There was a sequel too. It teaches you a fair bit to improve your confidence. I'd recommend you watch them both before your next track day. I'm moving to towcester soon, so I will be right by the track. Looks like lots of fun. Have a good one :D

[@TheMissendenFlyer]

+Matt McAlister yeah I have Keith Codes book - I gave up half way through!

[@mattmcalister1915]

haha, yeah a lot to get your head around. I'd stick though it though. You might find the videos easier to keep interest in :)

[@Ron_C]

Years ago I owned a Ducati Supersport 1000. I took it to a track in Summit Point West Virginia here in the US. I remember it being a very humbling experience for me. Looks like you had a lot of fun!! nice riding!

[@TheMissendenFlyer]

Cheers Ron and yes I know what you mean, just when you think you couldn't possibly ride any faster someone passes you like you are going backwards....makes me have huge respect for the Rossi's (and more so) the McGuinness' of the world!

[@MrSTAdventures]

Ducati's always sound so sweet when they are on full chat, nice one 👍

[@TheMissendenFlyer]

Thank you sir - will do!

[@dmartin23]

I totally and utterly love that bike

[@TheMissendenFlyer]

Me too :0)

[@UnknownProdrive]

Looks like a great day out. Thanks for sharing. I'm loving the intro with the nod from one camera to the other. It's getting more TV like presentation wise than an amateur vlog. Anyway back on topic. If you are lucky enough to own high end kit, track days are essential to test yourself and the bike. I defy anyone not to grin like a maniac under your lid out on track, great feeling.

[@TheMissendenFlyer]

Yes it was a great fun day - shame the rain came and put an early end to it though, wasn't brilliant value for money thanks to that....and thanks for the kind words re presentation, just my attempt to make the intro slightly less tedious but I've had mixed feedback! All the best - TMF

[@UnknownProdrive]

+TheMissendenFlyer The biggest issue with track days and value is time on track I agree. If you throw in iffy weather it can start to feel like a bit of a rip off. You're always gonna get mixed views on stuff comes with the territory. Presentation style is merely cosmetic from where I'm sat. Whats more important to me as a viewer is that the sound and picture quality are tip top which they seem to be so well done sir.

[@TheMissendenFlyer]

Well thank you again sir!

[@carlsmith5059]

awesome sounding bike,you overtook a good few riders before the rain came ,it looked a cracking day out

[@TheMissendenFlyer]

Yes she sure does have a bark about her when she hits 7000rpm, a real joy to ride on the track....and yes for some reason this novice group did seem pretty slow, maybe one or two more goes then I'll try the inter group....

It was a right hoot (if expensive once insurance got thrown in) - thanks for watching....TMF

[@theincrediblesulk5543]

+TheMissendenFlyer did you try Bemoto insurance I got my "08 GSXR for £80 with BVG discount

[@TheMissendenFlyer]

Yeah, I got my insurance with Bemoto, I just checked and it was £200.23 with a £2000 excess for the day...which I thought was pretty darn steep...

[@theincrediblesulk5543]

+TheMissendenFlyer Jesus that is hard to swallow. I suppose that is the difference between a 5k bike and a 12k bike. I guess you have to look at it as if the worse did happen you would be so thankful that you did splash out, it's the 2k excess that is taking the piss

[@TheMissendenFlyer]

Yes exactly, with the termi cans and ducati performance bits and pieces I paid nearer £15K for the bike and the thought of having someone take me (and it) out on a track day is pretty scary, hence why I shelled out...but it does make me think twice about doing further track days at £400 a pop!

[@stephenmcqueen4029]

Just came back to this video after watching your long term ownership vid. I’ve done quite a few TDS and fair play to you at least you had a go, saw 149mph and passed at least a couple of other riders. I’d like to see you do some more, they are great fun. Perhaps you could do the road bike only one at rockingham this year? Take no notice of the knockers. Some riders just won’t even try a track day.

[@TheMissendenFlyer]

Yeah I would quite like to do another track day or two - it's just the cost of the things once you include insurance for the day....

[@WoodyWood]

Thank you for that Ive always wondered what happened at a track day.I will never get to go on one as I don't have a bike and there is no way I would dare take the car

[@TheMissendenFlyer]

Glad you found it of interest Graham - did you see this one I posted a couple of months back? >> kzbin.info/www/bejne/oZbKd5aFo9Kbg6M

[@OpticDevice]

Graham Wood I know with MSVT (other track day providers are available) you can rent a bike and the excess isn’t too bad, 500 when I did my first one at Oulton Park. Just need a license and the right gear. Well worth it!!

[@JLOSTAFF1]

Nice one! Not my cup of tea, but still very entertaining to watch. Very well made in my opinion. As mentioned a few days ago, pick up my S1000R mid July - I know you don't like the headlights, but I think the bike looks quite cool! Glad you had a great time. Regards, Jon.

[@TheMissendenFlyer]

[@WEGGYZZR]

A good dry day on a cracking circuit......just a question.....what's the ruling on cam mounting" Track days"?

[@TheMissendenFlyer]

...depends on the organisers - on this one they didn't mind as long as it wasn't on your body, last one I did didn't want it on your helmet or the fuel tank...seems they make up the rules as they go along!

[@WEGGYZZR]

+TheMissendenFlyer So i had heard.....My local track is Snetterton which as you probably already know was another airfield a monster many others years ago.... One hell of a track..that I'll be back to shortly for the Bsb in July.....great memories of that particular track with the 1988 race of aces....first real time I see the Nortons cream all over the rc30's down the revetts straight.....but Then came the corners........Nortons didn't really like corners too much lol. anyhow is amazing looking back at the foggy wsb era on the 916 ....and looking at the specs of your bike.... 35 more usable ponies under the belt and razor blade handling.......what a track bike.... and of course road machine....rsmf

[@TheMissendenFlyer]

...I'm a Norfolk lad at heart (was brought up in the Long Stratton area) so I know Snetterton very well - did a track day there on my Street Triple a couple of years back, great fun and what a wicked straight! I reckon I could max the Panigale out on that one....must give it a try sometime :0) Thanks for watching and stopping by - appreciate your continued support. All the best - TMF

No restrictions, I'm just a rubbish track day rider!! Great fun though.....

[@glenwhyte2273]

so you didn't need to tape up your speedo? and also I take it they don't mind the mounted camera's? I'm hoping to get to Brans for a track day next year.

[@TheMissendenFlyer]

No need to tape up the speedo and camera's were fine at Silverstone - rules do vary depending on track and track day organiser though so worth checking in with the outfit you're going to Brands with to be sure....

[@MegaMaxymoo]

great content as always...out of curiosity how long have you been on two wheels?...pity about the rain :-(

[@TheMissendenFlyer]

...I passed my test about 5 years ago, so a newbie really, how about you?

[@MegaMaxymoo]

A year ago, so i am a novice newbie but building confidence and really fancy a crack on the track, is the insurance silly money?

[@TheMissendenFlyer]

Yep - about the same as the track day itself with a £2000 excess.....

thanks....ouch!!

[@TheMissendenFlyer]

...that's what I thought....

[@lloydperry3154]

Hey TMF I'm going to be doing my first track day soon. I've been reading alot of forums and decisions seem to be split on track insurance. what's your take on it? I'm not.looking at breaking lap records, just opening my bike up with out seeing blue lights behind me.

[@TheMissendenFlyer]

Well depends if you can afford to trash your bike and pay for it. I took out track day insurance, was extremely expensive, but wouldn't want to trash (or worse have someone else) trash my bike with no coverage...

[@adambainbridge1047]

Hey bud, did you end up changing your screen back for the footage? It came out well, just purchased a dark 'zero gravity' screen for my 959. It's the exact same shape/size only dark. Dreading the fitment as I know you struggled.

[@TheMissendenFlyer]

+Adam Bainbridge Nope, shot that through the darkened screen believe it or not...

[@thetugster9550]

How did the back tyre hold up this time ?

[@TheMissendenFlyer]

Pretty much the same as before, pretty shredded on the outside soft compound the harder middle tract held up fine - I'm a huge fan of these Pirelli Rosso Diablo Corsa's - once they're up to temperature they are very sticky and super confidence inspiring...

Something I have never done! I must get my finger out and give this a shot. Great stuff mate, and what a beautiful bike! I'd just be worried of "track heroes" all the time I think. How did you feel doing it? Were you nervous of others or anything? Cheers!

[@TheMissendenFlyer]

Hey Richy - ...and yes, even if you're not a massive track fan I think all bikers should have a go at this at least once. A bit like off-road riding, it really opens your eyes to the limits of biking and ultimately makes you a better overall rider as a result (that's what I think anyway). I did have a concern, not so much about coming off myself, but worrying about others doing something silly and taking me out....hence the track day insurance I took out this time. Anyway, recommended if you get the chance - Donnington isn't far from you and is a brilliant track....all the best mate - TMF

[@tigerjim6077]

Lovely video. Now which Panigale did I come on he says? Looks fantastic and really makes me want to get a 748r as a track bike. Do you find the speedo disorientates your concentration when you're on track?

[@TheMissendenFlyer]

Thanks Jim - No I didn't have any issue with the speedo, other than seeing it clearly (was a bit of a blur at nearly 150mph!). Track bike sounds like a good idea - this day was costly as I bought insurance for the day - added £180 to the track day cost!!!!

[@blademkd9778]

3rd gear 30mph 3k rpm i dont get it. any reason for it.

+TheMissendenFlyer worth it though. I'm tracking my street this summer but not sure what insurance to use.

I love floatplane flying, sadly you can't do any in England, there is one place in Scotland you can. When I tried it I flew our TB-10 over the alps into Italy and then rented a floatplane off of Lake Como - was simply stunning flying, would love to do that in Canada (I have close friends in BC and love it there)....

[@jeremias6769]

no offense, but you really need to grow a set of balls. why go on a track and then cruise through the corners with literally 3-4k rpm? thats too low even for a good sight seeing tour of silverstone... i am usually not the one to put people down, but with your riding skills you are better off with a bmw or japanese bike - an easy to ride bike. it is very easy to see that you are struggling with the bike itself and the panigale is already very beginner friendly. yes ducatis are nice bikes, but so far it looks like the bike is driving you.
