$2000 on gear for riding a motorcycle like twice a year a few miles on public roads... figures.
That's a Shoei helmet, looks like a Parameter. Costs about $550-$600 with those graphics. It's nice, but a perfectly good helmet can be had for $200. Now, someone who rides a lot or tracks a bike might find a lot of use in the marginal returns for a $600 helmet (slight weight savings, maybe lessened air noise?). But we know that Wu barely rides, if at all. I wonder if they got the bike registered since the last field agent went by and saw it had no plate.
The same is likely true of the rest of Wu's gear. You can spend $1400 on a jacket, pants, gloves and riding boots... but you don't have to, unless you want to have a bunch of each or have the expensive brand names for everything. A couple hundred for a jacket is easily done, same for pants and less for boots and gloves. Having that level of armor or gear is more typical of the track or perhaps someone that rides all the time, not someone that can measure riding time in how long it takes to snap a selfie.
Like with the cars, Wu sure seems to spend the most possible to get the least returns. He really does get a thrill out of spending Frank's money, doesn't he?
