This was truly lovely to watch. Glad to see the passion for customising and perfecting their motorcycles.

[@ChasingTenths]

@ thank you Ralph, that’s what I really love about this country . The passion for motorsport is absolutely amazing and the dedication plus know-how too

[@gonzalvezalvez6572]

Always loved the ZX7R, it never ages...unlike me.

[@ChasingTenths]

hahaha, love that comment, it's definitley a bike which is ageing like fine wine

[@raphaelmentrel1009]

Ritchie is a nice guy, and I love discussing with him. It's ZX7R is, by far, one of the most powerful and impressive ZX7R I've ever seen, and, this bike is a dream bike for a ZX7R lover like me. Thx for this video @chasing Tenth

[@ChasingTenths]

@@raphaelmentrel1009 much much appreciated, very kind words He has a heart of gold And it was a pleasure to meet him that day

[@neilchantry768]

Great to hear your coming out to race again next year And hope to see you and dad again 🤗👍

[@ChasingTenths]

I will definitely pass your lovely comment on to Ritchie Neil :)

[@EvanJohn-z2d]

i never realised the ZX7, 1996, made that much power. The Suzi 1000 K5 made 150bhp for 2005, which sort of puts it in perspective. Great bike

[@ChasingTenths]

@@EvanJohn-z2d exactly , that zx7R is a very special machine , all those changes made to the engine, exhaust etc etc has paid dividends

[@greenjackal4362]

Well now sir, I am baffled with these results. Not sure if you and I can boast or brag on this. On the same dynotune testing machine located here in Northern California my ‘16 RF in stock form, but for an aftermarket slip on (wanted before and after install of race ecu), laid down 196.5 to 197.5 . Shop owner said that is the strongest production bike he’s measured. Hope that Aprilia factoid brings smiles to your day.

[@ChasingTenths]

@@greenjackal4362 that is absolutely brilliant, and I agree with the shop owner.. the 2016 RSV4 RF engine is one of the strongest engine engines they built, and I’ll be honest with you that is a lot of power. That is a hell of a lot of power, I know the 2015 to 2016 Aprilia RSV4 RF really really well, and my bike only produces 178 bhp , you are a lucky man and that is some amazing power figures.

Great video Abhi ! Love your content , fan from Brazil here

[@ChasingTenths]

thank you my friend, all the way from Brazil wow, i think i have seen your comment once or twice before. I hugely appreciate your support all the way from there.

[@garymorgan628]

Great video and some awesome bikes, including your gsxr 👌

[@ChasingTenths]

thanks very much Gary :), much appreciated

[@berniethornton4315]

Super video Abhi. It was great to meet you at Matt's place - TBR Performance. It was a very enjoyable day, talking about bikes and racing. I was thinking of creating our own video from the material you shot, but you've done such a good job I dont think I need to bother! 😄 Thanks again, I'll keep you informed of future events and maybe we can meet up.

[@ChasingTenths]

@@berniethornton4315 thank you very much Bernie Wonderful words there Much appreciated Well definitely meet soon

[@IakovosSianoudis]

5:41 Why is the brake lever guard on the ZX-10R upside down?

[@ChasingTenths]

@@IakovosSianoudis they just put it on in a hurry , it’s normally the right way around for race Scrutineering

[@mmotorcycles9497]

Love the zx7 probably why a have a few of them but none have a awesome swing arm like that one

[@ChasingTenths]

@@mmotorcycles9497 wow that’s absolutely epic

[@kwakgreen]

I bought a 1998 ZX7R in 1999, I loved it, my missus made me get rid of it. In 2004 I bought a 6 month old ZX9R, I still have it today. There is no way I'm getting rid of the 9R.

[@ChasingTenths]

thats the absolute spirit. It's easy to sell but tough to buy again but i am so glad you have bought one again

[@stewness3863]

Great to see these bikes on here, the 7 is still my favourite bike but how good is that dyno run? Great bit of content so I am expecting great things going forwards on your media journey!

[@ChasingTenths]

Thank you very much , hopefully there will be some regular videos now and a bit of a variety. Even though subscribers numbers are mainly in doing constant bike reviews but i enjoy doing quirky and different videos.

[@io3204]

If the Zx7 has the crankshaft from the J model it is 792cc, for reference.

[@ChasingTenths]

@@io3204 ahhh , that’s very interesting, thank you for the info. I honestly wasn’t aware

[@io3204]

​@@ChasingTenths thx for the video. It is a rather popular modification for the zxr750 and Zx7r measured by the requirements. You can bore a Zxr to accept the zx7r pistons and you can put a zxr crankshaft into a zx7r as in the video. Both results in 792cc. The nearly 70ft/lbs (94nm) in the video are amazing. If you can somewhat hold that torque and make the engine withstand Wsbk rpms that bike would be going against 175hp. Greetings

[@ChasingTenths]

@@io3204 wow, honestly, I never knew this, everyday is a school day . This is the kind of information I would love to know more about I will do some research I know a lot about upgrades in general but not the internals of engine upgrade

[@io3204]

@@ChasingTenths Great. Btw, the last version of the Zxr750 chassis before they made the Zx7r would accept the first Zx9r engine with practically no or very minor modifications. It was basically the same engine with just bigger cylinders and more stroke to get to 900cc. So that was the most popular modification to the 750 as it was just a plug in engine swap to get to 143hp while keeping the sbk chassis and practically no weight gain. It is less revvy though. Great bikes and great video.

[@ChasingTenths]

@ priceless info this. You truly are a bundle of useful and unbelievable information

[@Zeebo1uk]

Welcome back brother

[@ChasingTenths]

Thank you very much mate

[@Roy_Godiksen]

I miss my old 2009 ZX10R. Damn that thing was quick. But as a street rider, it really wasn't a smart bike to own. No ABS or TCS, and a rev counter giving you the green when you're breaking the speed limit🤣 (The tachometer had a colored line around the rpm indicator). 💚💚👏🏼👏🏼

[@ChasingTenths]

I know exactly the bike / model you are on about Roy, i saw a guy racing that with NoLimits . to be honest that speedo and tacho is so unique to the kawasaki, even though they had no electronics but they were absolutley solid machines and so easy to tune and re map compared to BMW or Aprilia.

[@Roy_Godiksen]

@@ChasingTenths And back in 2009 when it came out, it was the fastest "liter bike" on the market. It was supposed to have a engine traction control system. Personally, i'm nowhere near fast enough to reach the limit of that thing without dying. But even reviews from MCN in the rain said they never felt it do anything. So, i don't think it was anything but a marketing thing back before TCS became a real deal.

[@ChasingTenths]

@@Roy_Godiksen thats a very very good point Roy, but i will be honest, every bloody time i have seen a review of multiple bikes, they put the kawasakies at the bottom and in the real world especially on track , they are the most popular race bikes to be on. Engine refreshes are cheaper, tuning is easy , parts arent that expensive and are easily available. plus dealer network is very decent. I love Kawasaki as a brand, i would love to buy the GPZ900R , the top gun bike one day

[@Roy_Godiksen]

@ChasingTenths I own a 1985 Kawasaki GPZ600R (since 2019). Best seating position on a sportsbike I've ever sat on. I'm sat down, almost in the bike. Probably not the best for racing, which is why modern bikes no longer have that seating position (modern is more on top).

[@ChasingTenths]

@ that’s true actually and that’s the best thing I like about retro bikes , you are part of the bike , it makes you even feel like the centre of gravity is low and bike turns better

[@flamintasty]

Hey Abhi, Ron at Maxton died at the weekend 😞

[@ChasingTenths]

Oohh no . I had absolutely no clue Thanks for letting me know , may he rests in peace. He did an amazing job to build that brand up

[@flamintasty]

@@ChasingTenths Yep, he was a legend. Richard learnt from the best, he couldn’t have had a better teacher.

[@hypermotardking]

Prefer the sound of the ZX7R

[@ChasingTenths]

It’s even better in person, screaming inline 4.. simply superb
