USEFUL WEBSITES - HONDA CBR250RR MC22
There are a number of useful websites you may or may not be aware of, which contain content and / or parts for the Honda CBR250RR MC22, including:
LiteTek
LiteTek manufacture and sell carburettor seal and gasket kits, chain sliders, and coolant hose kits for the CBR250RR MC22. They also sell parts for a few other motorbikes from that period too, including the Honda RVF400 NC35. LiteTek are located in Thailand, and was created by an Australian. We’ve purchased parts for both our CBR250RR and RVF400, so we can personally attest to their quality, their customer service is also excellent.
Keyster
Keyster are a well known (to some at least) carburettor kit manufacturer for myriad carburettor motorcycles. They produce OEM style replacement kits which include main jets, pilot jets, needles, float valves and fuel bowl gasket as well as tuning ‘Tornade kits’. Tornade kits have a number of different sized pilot and main jets, and needles for fine tuning the carburetors. This is very useful because it allows you a lot more variability in tuning the different RPM ranges of your bike than simply changing the main jets and altering the air/fuel screws ever will.
Keyster kits are made in Japan and we have used both their OEM replacement kits and Tornade kits with good success.
2Fiftycc
2Fiftycc is a forum with a wealth of knowledge for the CBR250RR MC22 and other 90’s 250cc bikes like the Yamaha FZR250 and the Kawasaki ZXR250. It’s one of the only (semi) active forums left.
Honda - Original marketing material (Factbook)
I recently stumbled on a very cool database (“Factbook”) on Honda’s Japanese website, which includes what appears to be technical marketing material which would have been prepared for the release of each new relevant model. The webpages are in Japanese, however if you browse with Microsoft Edge, you can turn on the translate function, which appears to be very accurate.
Clicking here takes you to the RVF400 page, while here is the CBR250RR MC22 page. There are a whole host of other models, in fact what appears to be all JDM models up to present! Enjoy. Some other examples include the CBR400RR and NSR250R.
Reviews
Here is a link to a Japanese review of the Honda CBR250RR MC22 from 2019. The review is in Japanese, so it’s best to open the review in Microsoft Edge, which automatically translates the review to English.
Below is a YouTube video of the CBR250RR MC22, with what looks like a new MC22 (the tyre tread is the same as the original tyres) although it may just be a mint condition bike. They start the bike up and rev it - it has the original muffler.
