Your thoughts...
馃い[drool]... GYTR - Get Yours To Race? 馃構 Does it come with a VIN tag? 馃槃 When will the third-party street-kits be available? They're also saying this will be "limited" so it doesn't sound like this will be an ongoing thing? Gonna be pricey...

At almost $20K, yeah, it's gonna cost more than some of the big boys. The spare $1,000,000 I'm planning to enjoy next year, I may just add one to the collection. We'll see. #goals #lusting

Now, I just need to get my hands on that spare million. I can taste it!



Yamaha probably didn't change much to the motor to keep it legal for the 600 class; that, and to keep cost down.

I'm looking at the 13.3:1 compression ratio of the 2020 model...
https://www.yamahamotorsports.com/supersport/models/yzf-r6

What's the minimum RON octane on this?
My '08 2nd-Gen is 95 and depending on the source is 12.1:1.
Does the 2020 model have anything like variable cam timing or knock-sensor?
(of course the '08 doesn't have anything of the sort)

For comparison/curiosity...

The R3, reported to run on 87 is 11.2:1

The R7 is 11.5:1. (haven't yet found an octane requirement on the review sites)

@Intuit, I'm not sure what numbers Yamaha's engineering department used for calibration. I do know their engineers know how to play with stoich, chemical composition, and combustion/thermo ratios pretty damn well. Well, every manufacturer does at this point.

That 13.3 seems extremely aggressive, but they've been doing it since 2019, so I'm sure it's solid. I'm guessing cars can get this extreme with the correct internals, timing and tuning. rubbing my hand together Can't wait to get a look at the stock mapping. 馃槑

Just curious what the octane requirements are; no concern about damage as these are extremely sturdy engines.

Long before I saw the "95" on my damaged specifications sticker in the trunk, I was having to run elevated octane in order to keep the plugs/cylinders from slowly fouling. Only after I noticed the relevant spec of undamaged sticker a couple of months ago, did I realize that having to boost the 93 octane, wasn't a malfunction. (Could've saved me a lot of time/money these past 60K+ miles.) Now the wiser, weighing the pros and cons of an R3 vs R7, I was looking at octane requirements. IF they have newer engine technologies such as VVT/VCT, knock sensor, minimum octane requirements become more of a suggestion for best performance versus a minimum specification or requirement.
