Heated seat and grips on a Harley Electra Glide Ultra Classic; sound systems?
I'm in the market for a new touring bike and I'm wondering how much of a difference a heated seat and grips make when riding on chilly or cold days. Are they essential, or are they just a trendy thing? Also regarding the sound systems, will I be able to hear music even with my helmet on? I saw one BMW rider who had either headphones or something in the helmet controlled by a handle bar control. Basically, what is the best way to enjoy music on a Harley?
The heated seat and grips are great if you plan to ride on just chilly days, but for truly cold weather or long trips on chilly days you need more than that. The key to staying warm out in the wind is layering. The space between layers of clothing trap your body heat and are much warmer than just one thick heavy layer. Don't be bashful about putting on two long sleeves or turtlenecks or sweatshirts before your outerwear. And don't laugh, a good raincoat is sometimes warmer than leather because it blocks the wind. In cool weather I carry some packets that can be torn open to make heat. Most stores like Kmart and sporting goods have them this time of year. Those have gotten me out of trouble when I strayed too far and too long on a cool day and it was COLD AND DARK heading home.
If it does't get horribly cold where you live you could get by with the grips and seat and they are hard wired into the bike so you just hop off and walk away without having to unplug any wires. If that doesn't give enough to keep you SAFELY warm, you can buy heated armchaps, leggings, gloves, vests at www.widder.com and at www.gerber.com and the local Harley dealer may have some in stock or at least in their catalog. I bought the insulated, electric Harley pants and they kept me warm in 34 degree weather. But, I also had the Widder arm chaps and vest and gloves as well. If you have the lower fairings in place you might not need heat on the legs for short trips, but on a long trip the cold will get your legs and you won't feel it until you try to get off the bike. BAD. once your legs are cold it takes a lot out of your body temp and a lot to get warm again. That is dangerous because you can get disoriented and just run off the road.
For music several of my friends in the HOG club use an MP3 player plugged into ear buds. They fit under most any helmet and still allow enough outside noise in to let you be aware of surroundings.
If you are feeling wealthy Harley has a handlebar mount radio/CD player with large waterproof speakers that can really belt out the tunes.
Hope that gives you enough info to make a wise choice.

Fragrance Oils and Essential Oils - What's the Difference?
Have you noticed lately that many household cleaning products and deodorizers are scented with “aromatherapy essentials” or with “Jasmine” or some other exotic fragrance like “Calming”? Do they really add essential oils to dishwashing detergent in quantities significant enough to be of any value and are they therapeutic grade? Well, of course not but with a growing popular interest in health and wellness, essential oils and aromatherapy make great marketing even when products only have artificially produced scents “inspired” by aromatherapy plant essences.
Most consumer products use fragrance oils to achieve their scent and although some mimic the scent of well known essential oils they are quite different.
Essential oils are natural and fragrance oils are synthetic
Essential oils are the natural aromatic oils that are extracted from plants. Technically they are not oils at all but complex mixtures of organic compounds that exist within the cells of the plant. Each essential oil is derived from a single plant source and depending on the species is extracted from the flower petals, leaves, stems, roots, rind of the fruit, seeds, or even the wood of trees. It is likely these compounds have evolved over time to aid the plants in survival by providing resistance to disease or by attracting pollinating insects with their fragrance.
Fragrance oils are man-made organic mixtures that are engineered by chemists to produce an attractive scent. This can be anything from “Lilacs” to “New Car” scent. Although fragrance oils may contain essential oils as ingredients they will also contain animal and synthetic fixatives, and synthetic compounds derived from petroleum.
Essential oils are therapeutic and fragrance oils are not
Essential oils are not only fragrant but they are also therapeutic and have been used for centuries, medicinally and cosmetically to improve physical and psychological health and well being. Specific pharmacological effects are produced by essential oils through skin absorption and inhalation, which is the very basis of Aromatherapy, a widely used form of natural alternative medicine.
Fragrance oils are used to scent hundreds of consumer products and their sole purpose is to improve the smell of the product. Although fragrance oils may contain many ingredients, they are biologically less complex than essential oils and provide no therapeutic benefits.
Why do most commercial products use fragrance oils?
With such a profound difference, why do most commercial products use fragrance oils and not essential oils? The main reason is cost but there are issues with supply and the range of scent as well.
The harvesting of plant materials and the production of essential oils can be very costly. Some plants such as lavender are grown on commercial farms and are harvested mechanically. But many are hand picked and in some cases from plants that grow in wild habitat. The yield of oil from the plant material is very small and can range from as much as 10% to as little at 0.02% by weight. The highly prized rose and jasmine essential oils are both derived from hand picked blossoms that yield only 0.02% oil by weight of fresh blossoms. Fragrance oils on the other hand, can be mass produced from relatively inexpensive organic chemicals.
Being crop-based, the supply of plant material and yield of oil will vary from year to year and some plant species have limited habitat. The supply of many essential oils is too limited and unreliable to economically serve the needs of large scale commercial production.
The essential oil industry is analogous to the wine industry. The quality of the final product will vary according to the plant subspecies, the growing conditions and the manufacturing. This variability is not suited to the mass production market.
Only a very tiny percentage of plant species can economically yield usable essential oils and although the range of scent is tremendous, all essential oils have a “natural" fragrance. So if you want to produce the scent of “fresh baked bread” or for that matter “Lily of the Valley”, you have to use fragrance oil.
Are there products available that use essential oils?
Yes. Essential oils are the perfect choice for adding fragrance to skin care and bath and body products that are made with natural ingredients. By selecting the right combination of oils, it is possible to achieve a wonderful scent and also enjoy the therapeutic benefits of the oils. The essential oils complement these products. They treat many skin conditions, contribute to healthier skin, relieve aches and pains and have a balancing effect on your mood and sense of well being.
Natural perfumes made exclusively from essential oils can also have a positive effect on your mood. They can reduce anxiety and stress, combat fatigue or be invigorating and stimulating. They tend to be softer than most commercial perfumes produced with fragrance oils. Essential oil based fragrances are not overpowering, and are less likely to irritate you and the people around you than commercial, synthetic scents.
If you enjoy fragrance, but are sensitive to certain synthetics and chemicals, essential oil fragranced products are a good alternative.
It's your choice
Knowing the difference between fragrance oils and essential oils is an important first step in deciding which products are most suited to your needs. Mass produced low cost consumer products will use fragrance oils to produce an attractive scent. This is perfectly acceptable for dishwashing detergent but shouldn’t your face cream use pure essential oils? Don’t be fooled by the marketing. Read the labels carefully and make your choice.
