Something close that is off the shelf
There are other models available for trail motorcycles.
:-P

But at least the abc and others but some of the good stuff onto their websites like

You are not storing a single large number but a series of digits.
Pics and other similar chips are 8 bit so values per register are 0 - 255 or 0 - FF in hex.
So use a register to store each digit (0 - 9).
For a long term solution I'd recommend storing the values into a serial eeprom or other chip on power off. A decent sized cap would give power for long enough to write the latest value.
few circuits
Doesn't have to be a pic , could use atmel avr or other micro.
Do you know any programming language ?
Dontronics.com sell some cheap pic boards(and avr and others) from olimex.
If you use an 18f or 24f or 30f pic , microchip have c compilers for them.

What a pity about that speckled background, which makes it much harder to read IMHO
It will depend on the type of flash, however eeprom has a significantly higher endurance than flash memory (several orders of magnitude). I quoted the endurance (write cycle) figure for the flash and eeprom in the PIC micro. The endurance of your memory stick and camera card may be the same, but it also may be less. It is probably anticipated that you won't be writing to this piece of hardware in 10 years time, let alone 27. Micros on the other hand have a tendency to sit in a piece of equipment for a bit longer (20 or so years in some cases).
Since the odometer value is only 3 bytes, it makes more sense to save it into the on-board eeprom in the PIC.
