International Motorcycle - "... you could learn an awful lot from this remarkable series of motorcycle instructional videos ..."

Australian Motorcycle News - "... After a 30 year involvement in motorcycling, I still found the Sweet Spot motorcycle video series both informative and entertaining, these videos will do much to fast-track their knowledge and skill."

BikeNet - "Within ten minutes of watching these videos, we realised that we could probably halve all the mail we get from BikeNet readers with "Techtalk" enquiries ... The Sweet Spot Video library comprises 9 hours and 45 minutes of video, covering everything from Track Preparation, Suspension and Tires to Motorcycle Hygiene.

The two we received to review were Tires, Chassis and Suspension, and Dialing In. Very professionally made, they go into great depth about how to set up damping, spring rates, carburetion jetting, tyre types, gearing and so on - particularly for setting up under race conditions, but also relevant to the street. Using recognized industry experts, such as Dale Rathwell of Yamaha and Ken Williams of Michelin, National US Sprint Champion Kurt Hall rides a bog-stock Yamaha YZF750 around a track, and the mechanics and experts go step by step through the setting up process. You're not shortchanged on time - each video runs between 60 and 113 minutes, and the depth of detail is really excellent - even old pros like us found something of interest. There's on-board motorcycle video, very clearly shot, showing the suspension doing it's job and Kurt is obviously not hanging about as you see him sprint past the other people on the track during a test session.

Occasionally the action gets a little slow, but this is probably just because they were covering topics which were already familiar to us - for many readers this won't be the case.

And don't think just because it's all track based that the lessons can't be applied to your bike - the basic knowledge applies regardless of where you're riding.

What more can we say? Professionally produced, accurate information, well edited and shot - essential viewing!"

Sport Rider - "The proliferation of videos on the market today reflects the growing popularity of manufacturers' use of visual media to educate consumers. Instead of a lengthy brochure, many now produce a video to show their wares, or use them to demonstrate the proper operation of a particular product.

The Sweet Spot motorcycle video series is a six-tape library covering various motorcycle components with the modifications that will benefit you the most. Everything is dealt with, from installing a pipe and jet kit on up to prepping a production motorcycle for the roadrace track. Most of the major fundamentals are covered in the videos: motorcycle exhaust and carburetion, suspension, and tires. Other videos cover related subjects such as motorcycle lubricants, bodywork, and chassis setup. Each edition has several acknowledged experts from each field to give a detailed analysis on the subject, with demonstrations and examples to assist their explanations.

For experienced experts, the videos will have little value, since only the basics are covered. The series will mostly benefit the novice rider who is interested in learning more about his motorcycle, and is possibly interested in roadracing. The videos have quite a bit of valuable information that a novice or even intermediate rider can put to use, and all of it is shown in a concise, easy to understand manner; and they won't break the bank."

Two Wheels - "CORRECTLY setting up a sport motorcycle is one of those black arts which can cause normally sane and rational individuals to develop sufficient psychotic traits to keep a shrink enthralled for months.

Modern sport motorcycles have an enormous range of suspension adjustment built in as standard to make fine-tuning a DIY proposition. However, the apparent complexity of understanding the relationships between, and effects of, preload and damping systems forces many owners to venture no further than the standard settings.

And that's just for street use. Getting a motorcycle set-up for roadracing opens a whole new box of potential problems and frustrations.

This is where the Sweet Spot Video Library could come in very handy. Sweet Spot is a series of six motorcycle videos - each approximately 120 minutes long - which deal with pretty much every aspect of motorcycle set-up, from choosing the best riding gear to dialing in motorcycle suspension, carburetion and exhausts, cleaning and lubrication.

The American-made series covers the step-by-step preparation of a Yamaha YZF750 for roadracing, and while the information given has been selected and delivered with that end use in mind, there is still plenty of useful stuff for the street rider to glean.

Host Jeff Haynor directs the transformation of the YZF from stock street motorcycle to Supersport 750 roadracer, calling on a varied line-up of experts to guide him and the viewer through each individual step.

Perhaps the most useful aspect of the Sweet Spot motorcycle video series is that it goes a long way to answering the kind of questions that everybody has about motorcycle set-up but were always afraid to ask.

For example, I learnt heaps about finicky little details like lockwiring, motorcycle jetting and fine-tuning carburetors, fitting braided brake lines and installing aftermarket bodywork."

Motorcycle Consumer News - "Experts will tell you that motorcycle roadracing success is as much about knowledge as it is about personal bravery, and access to this much professional advice could cut months, or even a year of expensive and frustrating expensive and frustrating experience from the average roadracer's learning curve.

If you have a desire to roadrace, but would like to go to the track with enough basic knowledge that you wouldn't feel foolish asking further advice, several or all of these videos, at about the cost of a new rear tire, could be money well spent."

Dealernews - "The series targets sport-bike enthusiasts, motorcycle dealerships, motorcycle performance shops and racers interested in obtaining maximum product and machine performance ... the series combines the knowledge of industry leaders and roadracing experts, who deliver facts and give answers based on race track-proven directions on achieving maximum performance ..."

Motorcycle Performance - "I settled in for what I thought was going to be a story book movie of home videos taken in a garage somewhere. NOT! It even came in stereo. I cranked up the sound in my home video system and started on my bowl of popcorn.

I didn't start with the first video of the series because I wanted a flavor for what the videos would do for me, not what I was supposed to learn. That was my first mistake, I should have started at the beginning and gone through the series in succession so I could build upon what I was supposed to have learned from the previous video. But you learn from my mistakes.

This video was amazing! (Performance Systems) I thought it was going to be an infomercial for some oil company, but realized that the Sweet Spot video series was not pushing products, they were pushing knowledge. That's right, knowledge. Something that I felt I didn't need, but was humbled greatly when I admitted to myself that I wanted to know more. I was hooked on this video already. I know of some really good mechanics who I bet don't know this stuff either.

Track Preparation (Motorcycle & Rider Roadrace Preparation) was next. This video dealt with all the necessary paces your motorcycle needs to be put through before going to the roadrace track. Remember that these videos were designed to give you a baseline for performance enhancements to ride in the Sweet Spot. The video started off with an important part of roadracing: the protective clothing we all should have whenever we ride a motorcycle at the track or on the street.

This video also broaches aftermarket body works and how to install them. If you are a roadracer, this will interest you. How to lighten your bike by removing unnecessary parts I had never thought about. They even explain how to install a Dzus fastener to body work. Now where can you get that kind of expert knowledge without asking someone who has done it before? They went into what to do and what not to do so that your installation is a complete success the first time.

Remember Rod Serling's Twilight Zone opening monologues? Always concise, but informative, Serling's piece whet the appetite for more. Jeff Haynor, the man behind the motorcycle video biblioteca Sweet Spot Series, does the same for this informative group of videos. 'The objective of the series is to show you, step by step, the process of establishing a baseline and then going from that, to dialing that particular component in. So whether it's on the street or at the track, we know that the information you receive from this video series will benefit you in handling and performance and insure you will consistently ride in the Sweet Spot'. My opening would be a lot less profound. "Watch these videos and you will know a whole bunch more than you ever imagined about a motorcycle."

Dale Rathwell (Tires, Chassis & Suspension) begins with the motorcycle suspension basics: shock springs, the functions and theory of operation. He discusses pre-load, how to adjust shock springs, and their effects on the motorcycle, both front and rear. What is free length, how to adjust and measure, installed length, how to change damper settings.

About now I had to start taking notes and rewinding to make sure I missed nothing. Did you know that rebound in a shock dissipates the stored energy of a spring? I also learned how compression damping adjusters worked.

Rathwell went into the hard core stuff on motorcycle chassis fundamentals like how to have straight wheels by making proper rear chain adjustments and how to measure rear wheel alignment. He shows you how to measure from the swingarm pivot back to the axle instead of relying on those little marks on the chain adjusters. This man knows his stuff and he gets excited telling us about it. You'll learn how to adjust the chassis for a particular track or riding style, how to raise and lower both the back and front of your motorcycle and how it affects your riding and handling, how to change the ride height and why you would want to.

Think you've had enough? Rathwell embarks on a detailed explanation about a plethora of items: motorcycle fork oils, springs, how to trick out a component, disassembling fork tubes and learning what every component in the fork does. Learn about flow valves, check valves, control holes, valving a fork piston and shim kits. He tells why forks are inverted and what that does for a motorcycle.

Carburetion & Exhaust Systems was also more than I expected. Marc Salvisberg of Factory Tuning Components explains the different motorcycle exhaust systems from slip ons to full header exhaust systems. I even learned how to non-stress mount an exhaust system. If you are going to install a full header exhaust system, you really need to re-jet your carbs to get the most performance from your motor that the exhaust system will allow. You will learn how an aftermarket performance header and exhaust system can cut as much as 19 pounds off the weight of your motorcycle.

Salvisberg meticulously goes through the complete (and I mean complete) disassembly procedure of getting to your motorcycle's carbs and their removal. You learn about choke jets, main jets and pilot jets. He gives the theory of a carburetor and what role each of these jets play in the carburetor. You go through the complete installation of a stage 1 jet kit, including setting the needle height and where to insert the needle C-clips. Anything you want to know about motorcycle carbs is here.

This series should have a warning label on the side like tobacco products. As the self proclaimed Technical Information Surgeon General of Motorcycle Performance, I must warn you, watching these videos can be informative, fun and very, very helpful getting your motorcycle into the elusive Sweet Spot."
