I considered fitting a gear indicator on my ST 1300, until I read a post here in the forum by an older and wiser owner who made the following comments:
- If the speedometer needle is higher (in 'clock position') than the tachometer needle, you are in 5th gear.
- If the speedometer needle is at the same clock position as the tachometer needle, you are in 4th gear
Michael, I suspect the post you read was not by me, but certainly could have been. In fact I'd been plotting when to write it after learning to my dismay how the clocks on the 1300 behave. This is one of my real annoyances with recent Honda vehicles, including Acuras. I've been a solid Honda fanboy, both 2 and four wheel for a long time. In all my manual transmission rigs prior to the ST1300 I could count on the following as you ran through the rev range.
- One gear down from top - needles are parallel
- Top gear - speedometer needle leads tach
- Two gears down from top - tach needle leads speedo
This design choice was good for my CB400F, V45 Interceptor, ST1100, 88 Integra, 91 Integra, 2001 Civic... until the ST1300

And my 08 Acura TL violates that too, but it has a slushbox, so it really doesn't matter.
This is the first vehicle where I'm still haven't internalized the engine sound, vibration and road speed and calibrated against the gear position. I'd like to think it's not due to age.
That said, I did order a gear position indicator for my 1300 last week and it's due to arrive from GUANGZHOU, CHINA today. I looked at the GIpro by Heal-Tech but for just a silly 8segment LED and some simple electronics, it's eye-watering expensive at $159.99 from sportbiketrackgear.com.
I found this on Amazon.

It's one of the few sellers that support and acknowledge the change in the bike following the 2008 model refresh. Once it arrives I'll write up a report and post it here. It's only $44.50 with slow boat shipping. I paid an additional $9.99 to get here in time to install along with my BLUEGAUGES.COM LED backlight upgrade.
Oh, and it does plug into the ECU diagnostics port.
I buy local as much as possible and prefer to reward companies that develop and market a product that's new and innovative, but $160 to see what gear I'm in is excessive even without the copycats.
