Newbie question about restriction

Don TZ said; "Speaking of racers, I have a group-buy underway with some 400 (US 1WG) pilots for purpose-built race harnesses ..."

Which is relevant and brings us back to the questions asked earlier in the topic, re. the speedlight,the TCI and the exup plug connections on US supplied Genesis models.
It is also linked to the Ignitec questions being posted in the general section contributors being Kayla, Wrax and of course himself.

Does a race harness stop you falling off ?

[DonTZ125]

Depends if you have the matching connectors on your leathers ...

US spec FZR400s do not incorporate the "speedlight". I've only encountered a restricted bike once. It was an RGV400 that I was riding in Thailand. Talk about a let-down. Imagine the frustration of riding a restricted 2-stroke while trying to keep up with my buddy on his GSXR750... That little red light was relentless.

The US FZR400 EXUPs have a control box separate from the TCI that plugs into the main harness. The TCIs for the EXUP models look the same as the non-EXUP except for the part numbers. They both seem to run just fine with-out the speedometer for all of the racers over here. I would expect the 3EN electrical to have more in common with the California FZR600 EXUP models. I had one of those, but it was stolen in 1991, so I don't recall a lot of detail. I haven't heard of restriction issues for FZR600s.

If Yamaha managed to do away with restriction circuits in the 4DX box for the UK market, I would think they would do the same for US bikes.
