Red cows (or leather) are expensive
I just got my Joe Rocket Hyperdrive Tall 54 jacket at Motorworks for around $350 incl. tax (ymmv.) It ROCKS!
It has NICE leather, all except carbon shoulder pads. All 3 removable pads (I may replace from an older jacket with better pads - pads is ONE place they save some money - that's ok, I've got older jacket better pads), nice SOLID leather forearm pads with big JOE ROCKET on it as well as NAME posted on the back too (While not in red leather strips, it looks slick), and two button straps per arm: bicep and middle forearm. The arm length may be a little too long, but it is no big deal to me. The main zipper is NICE AND BIG, unlike the Joe Rocket Sonic 2.0 (which also has drum died leather that looks like suede that you can't wash, use saddle soap, or treat like nice leather as on Hyperdrive coat).
The ventilation is good on the arms (90 degree weather today no problem, while moving - but filling up with gas, you break a few sweat beads on your forehead with helmet on.) The Sonic 2.0 is supposed to be better aerated, but can't clean or treat leather (i.e. - not top leather.) The Strength and Speed hybrid leather jacket for $300 retail was the lightest of all, but may catch colds in cool weather because too thin/aerated: as well as it tears easy and only goes to a 2x size.
Everyone who saw my jacket today complemented me on it, and I was the only one at Motor Helmets who had a leather jacket on (because it was perforated for the most part.) So between the Hyperdrive, Sonic 2.0, and S&S Top Dead Center jackets respectively:
Temp - full warm to cool + slight hot; hot to warm + slight cool; warm to hot + no cool
Price - $350; $367: $299 + tax
Leather - All NICE leather; One shot drum died leather; hybrid leather and textile (mfg. defect in leather perforation process )
Looks - Top leather and top dog; nice looking leather if you don't know the different grades; decent looking blue (red and white too I think) leather hybrid but it may be drum died leather too to keep costs down along with textile composition.
Most all other Perforated leather jackets (not on Ebay from China) start at $600 up to about $1150 (and many of the $600 ones were bybrids too - for skinny dudes or dudette's.) I tried on the S&S jacket on at Motor Helmets and walked around the store (real light jacket but was afraid of catching cold when it was cool), spent $8 for return plus a couple of hours time on the Sonic 2.0 jacket sending it back (which the wrong size made me look at zipper and leather quality before sending it back, THANK goodness), and then just ordered the Hyperdrive jacket from Motor Helmets long size 54 chest and picked it up - that was easy (never worry about waist on Joe Rocket jackets.) The Hyperdrive jacket fit comfortable with the liner in, so I knew w/o would be a comfortable fit. Nothing could have been easier, plus I get the 2 to 3 extra inches of bodylength on the long jacker (which the Sonic 2.0 also had available, but only up to 3x or size 54 chest.)
The Hyperdrive is definitely the nicest jacket I've ever had, and looks even better too. I walked about 3/4's of a mile in it today in the 90 F degree Sun. It was not the most pleasant experience, but all the squids riding in long sleeve shirts seemed to be amazed that is was not sweat stained, like I was amazed their shirts were not blood stained, ha ha.
Most of the other sites could not get the size AND the make of coat I wanted, so give Motor Helmets a buzz and ask them for the deluxe tall (true Chest size) Joe Rocket Hyperdrive PERFORATED (model) Leather Jacket. If you live in the South and esp. SO CA, you will love it (year round!)
And cooling your belly, like with S&S jacket, in Eastern medicine can cause serious digestive diseases that effect the whole body. Health originates and ends with your stomach!
