Its a brake bias adjuster. It allows you to put more stopping power to the front or back as noted. Its used to allow you to control how the car handles based on weight distribution, personal preference, driving style and whether or not you want equally distributed brakes or are trying to achieve oversteer or understeer. Oversteer allowing you to corner faster but have a tendency to slide the rear tires. However, if done right you usually go through the corners faster. Understeer allowing you to be more stable while turning but feeling slower in the turns and feeling like its harder to turn. It also saves wear on tires and allows you to accelerate out of corners more quickly and stably. **edit** All of this is probably obvious but just wanted to mention... It also depends on the surface you're on and obviously the type of race or driving. Daily driving you'll probably lean towards oversteer to make it feel more responsive and like what most think a racecar feels like. Rainy driving understeer is probably a better option because of the stability, especially with a manual. Drifting, circuit, rally, dunes, mountain dirt trails... Etc. All have different feels and each driver feels confident with different settings. Some guys are insane and prefer the ass end to be loose coming around a loose dirt hairpin at 80 others prefer not to tempt fate lol.
@@OperationRacecar more pressure to the back causes oversteer by locking up the rear tires and causing them to lose traction first. Think Tokyo Drift. The rear end loses traction first causing the car to slide out and they have to drive through the turn with the rear end sliding with no traction (aka drift). Granted they're typically using an E-Brake to get the lockup but it still illustrates my point. Rear wheels lock, lose traction and then slide. Unlike understeer where you are literally being "pushed" through the corner by the back end of the car. Front brakes lock up, slide and now you can't turn as well. Think about when you were trying to corner really fast but no matter what you did it just kept pushing you to the outside of the turn. That's because the front end doesn't have traction and the rear wants to keep going straight.
f1 drivers adjust their brake bias for each turn with pushbuttons on their steering wheel. Always thought it was crazy that those dudes not only have to maintain driving the car down the track, but all of the other little functions they're doing on the steering wheel at any given moment.
I think thats why the sierra cars haven’t taken off like everyone thought they would. I remember seeing them being developed years back and everyone thinking they would be the next massive thing in racing. The entry point is crazy high for the common weekend warrior who could do a TON of other stuff for 50k.
6:32 its a brake bias adjustment knob. Weight transfer from back to front under heavy breaking can cause the front tires to push (oversteer). Most vehicles transfer 70-80% of their weight to the front tires under heavy braking. This is why more front brake bias is typically better. A good starting point is 60% front 40% rear. If you have too much of a rear bias you will wear out brake pads a lot quicker because the weight is transferred to the front under heavy braking. This can also lead to the rear tires locking up under braking because the center of gravity of the vehicle is transferred from the rear to the front reducing traction. So is best to have a front bias.
6:40 Obviously, on any type of bike, one does not want to go flying over the handlebars. However, on both standard two-wheeled vehicles (one wheel up front, and one in the rear), and four-wheeled vehicles, the front brakes will always provide more stopping power.
the brake bias can totally change a vehicles handling characteristics, on rear wheel drive I like 80-85% front bias, braking before the corner transfers the weight forward helping the rear get loose and swing round. You will know the correct setting when you find it.
I built a street legal Sandrail in 1986 using a VW front end and rear transaxle. It weighs 975 lbs, with a big bore kit, dual dellorto carbs and 4-tuned exhaust around 75-80 horsepower. Very quick to about 80 mph and then the wind resistance takes its toll. It cost over $5,000 then, the frames have tripled in cost (Hi-Jumper "Sand Sprite II"). Virginia.
That's the way to do it. I've always wanted to build one. I have access to all the equipment now, tubing benders ect. Just sucks now because material is stupid expensive now.
@@michaelcarter3149 my dream would be a single seat tube-frame with fully independent suspension (I prefer street over dirt) using my 2012 GSXr-750 engine and transmission; it has less than 800 miles and is roughly 150 horsepower. I live very close to the Blue Ridge Parkway and just know I would be tempted to take it through the curves; Speed Limit is 45 mph ... better not 👎
@@frederickwoods5943 That would be the hardest part about owning a vehicle like that. Especially driving around there. I'm in NW GA, I know exactly what/where you are talking about lol
@@michaelcarter3149 I am at the northern entrance heading south on the Parkway and ride motorcycles plus drive my Mini Coopers, new pavement that is smooth; know the Rangers and they know me (age 72, cut my teeth driving it and usually very little traffic 😀).
When I was looking into buying one I looked to make it off-road and it was gonna be around 65k so I just bought ax3 with a wide axel and spring kit for 45k
the brake adjustment is to help stop from locking your wheels up in front or rear depending on how ur driving weather ur racing it or ur in and out of corners ur don't want ur front steer tires locking up when ur exiting and entering corners you adjust it for ur style of driving
Helpful all around tip: Buy a modern simulation racing video game, and play it. Much cheaper way to acclimate and experiment while learning what not to do. Plus it’s kinda like exercise, for your mental muscle memory. Which translates over into real world understanding, like oh this is what that meaning does
Hey you really dont want to remove those window nets because god forbid you ever roll that crosskart over in an accident, those window nets are the only thing stopping your arms from being forced out the window and getting crushed by the vehicle! So unless you dont want your arms anymore, i would use the window nets!
Honestly I'd put heavy duty nuts in there if you're driving that thing on the street going to like Nascar or professional drivers use that looks more like a mosquito net
The price is mostly because its not manufacturing at high quantity, mostly fabricated by hands, and the amount of people who would want to buy that will never justify creating a Toyota style manufacturing line.
$50k seems a little steep considering the build cost but then again there’s also a lot of time that goes into making it what it is and work 100%. Then you have similar cars like the DF Goblins going for ~$30k so idk. I suppose it’s relative when you look at the purchase as a toy or track car.
@@OperationRacecar had a Busa long ago and it was insane , been riding my whole life and me on that bike was like drivers ed students in Corvette's , sold it after a few thousand miles
Whats the insurance situation like for this? I'm sure there are specialized insurance providers? I can imagine that the premiums are going to be high but hopefully not crazy. Either way this thing is awesome and I want one!
@@OperationRacecar that is a smoking deal I would be willing to bet you've been with that company and have had that agent working for you now for quite some time huh.? Anyway enjoy forever and start learning all about the things so you can start maintaining it yourself I guarantee you purchased years worth of fun right there for only 50K good for you.
Honestly don't know brother! I sold my cars. I don't think they make the gas motor version anymore, but you'd have to call them to verify that. Best of luck brother!
@@OperationRacecar im pretty sure they don’t which is why id have to by one pre owned which I don’t mind doing if i have to i could buy one with a blown engine and rebuild the engine
@@OperationRacecar Reverse would be a must for myself driving it as a street car but for racing going backwards, well you know. Also I seen a post about needing to use the window nets so you don't crush your arms in a roll over. Speaking from my personal experience in a rollover crash going 85mph my arms never decided to leaving the vehicle without me, this wearing a standard seat belt not a harness like you have. Side note my windows were rolled down at the time, not that it matters because the other windows that didn't roll down were shattered from the weight of the vehicle flipping onto the roof. Again my experience
@@Kirk_Wood I appreciate you sharing your experience. Good points! Yeah, I get the point of the window nets....but its such a small car and I can't drive around with those nets up haha.
Those net "windows" are great for some minor rocks and mostly branches, so when going through woods, you might really want to have those up. Nice that it has a key, but, honestly, it's probably a really crappy lock that can be picked in no time, like seconds, certainly under a minute by a lot. Honestly, adding a killswitch somewhere with those crappy red plastic keys in a spot that really doesn't show might be a better idea, they just won't find it as fast. Like between the side panel and the chair down low where you can just reach, under the seat, something like that. Another one on the outside might be an idea in case of an accident so people can switch it off, but you'd have to take that with you because if people steal that to screw with you that is very annoying, and your friends will be annoying at times as well, just to screw with you too. But, this looks like a hell of a machine, but it's a lot of money. For fun. So you'd really have to have expendable cash.
More brakes at the front = better braking More brakes at the back = funner braking with skids and stuff. Less front brakes in dirt as it will lock up easy and make it so you can't turn. Back brakes on dirt allow you to turn still. I would keep it roughly 80% front and 20% back, when you brake your car... Or whatever this contraption is, will transfer weight forward making front brakes better and back worse. Also if you need to use back brakes to skid, you always got the E brake
The 'Busa hasn't been the fastest street bike in many years. To my knowledge, I think the newest Lightning is the king of the hill, and has been since their release to the public.
Very cool was actually on my bucket list till I saw the price then I was just gonna stick with building my own I mean it’s not like I can’t afford it but it cost as much as a rolls Royce now or a Bentley continental
If I heard you correctly about your seat belts, dude, this is no joke. Don't even drive without buckling the lap straps. If you just have the shoulder and sub (submarine) straps buckled, you will literally rip your junk off. I taught racing for 20 years and have seen a lot of carnage. You are better off using just the lap and shoulder straps. DO NOT use the sub strap(s) without the lap straps.
Please just remember when you're driving down the street you do not want to ever get hit by a full size car or truck or mini truck because that cross card never went through crash testing and whatnot in other words if another vehicle hit you on the street you will more than likely be killed. Have fun rip and rip it up
Dude you gotta do the four points on the restraints trust me you don't wanna rack your nuts like that it could be really bad for them. Just saying man I crashed bad with 5 points but I only had the lap part on it. I sure wish I had the shoulder straps on 😅
thats what i was wondering! if this was streetable and off road with Can-am Maverick (for example) level performance it would definitely be a must have!
I'm confused... this is a Hayabusa engine but the car only runs up to 120? (according to their website). I believe it also weighs 1000 lb but is that the only reason why the top end isn't that great?
Bro... The one thing that made me mad is that you said you haven't drifted yet... You have a $50k supermachine... And you haven't drifted??? Please... This thing is built for it... Please go!!!! Drift!!!! Don't be selfish..
This thing is insane. It's about the same price as a full size Ford f250 or a Tesla. Honestly it's probably only something for a person with extra cash to burn. I would definitely buy one if I was single and had some disposable income.
