Hrc Swingarm Upgrade...

Honda's HRC Swingarm is a worthy upgrade for an RC45 and it's an easy

bolt on Mod if you happen to have all the kit parts specified in the

HRC manual... like HRC kit shock... HRC kit suspension linkage... HRC

kit brake hanger and so on... but if you don't have the parts then

it's a pain in the butt to interface one kit part with all the other

stock parts... so it was up to my own skills to engineer and machine a

list of parts to interface the HRC swingarm with the stock Honda

parts... consequently Mr.RC45 has been up on blocks for a couple of

months while the Lathe and Mill turned out the these parts... enjoy

the picture show...

It took 9 days of sanding and polishing to remove all the rough

casting marks and bring out the luster of the aluminum...

Excellent craftsmanship as usual Larry, looks great! :wheel:

Now next time you test the off-roading abilities of Mr RC45 you'll have 2 less pounds to deal with! :beer:

Just messing with you Larry! :cool:

Larry,

Anything left stock on that poor bike, or are you saving up parts to make a new RC45?

BTW, did you get that unobtainium wheel?

That swingarm looks awesome. All that sanding and grinding must have removed some additional weight. Did you happen to get a before and after weight on the swingarm?

Thanks Bailey... but 2 less pounds means more frisbee time...

Test hop postpond due to thunderstroms which allows time to do a weight and

balance study while the tank is empty...

ps - does this swingarm change the wheelbase in a belt-drive favorable manner?

HRC swingarm is the same length as stock so no joy on the belt drive conversion...

I have 5 pages of mods which covers just about all of the stock

parts... and yes... all of Mr.RC45's parts are cocooned for

prosperity...

My 3 spoke MARCHESINI magnesium wheels have a pedigree story...

The 6x17 is a spare off Freddie Spencer's Two Brothers sponsored

RC30... and the 3.50x17 is a spare off Jimmy Flice's TZ250 sponsored

by Wayne Rainey...

Just beautiful :cool: well done Larry :beer:

Did you weigh all parts involved, both the before and after parts?

I bet Larry goes to the men's room at every opportunity during a ride............ just to keep the weight down.... :wheel:

Very nice!!! How about some rear sets, that would be another unique mod to add to your list!

You're looking at my Rear Set design...

Larry, please spend some of your valuable time thinking of more farkles for us regular VFR folks...Your peg lowering blocks were great (I bought them) but the community needs more cool stuff.

Great work on the RC45.

Rear sets...I couldn't tell from the pics at the top of the page that they are a one-off piece. They are quite nice!!! I'm still looking for some for my 4th Gen. It has been said that the mid 90's Aprilia's have the same distance between mounting points for their rear sets. If that isn't the case, I may buy some Sato's and just have new mount plate made up that matches the VFR's dimensions. Yours are very clean, very nice!!!

Wow, magnifico. Mr RC45 is by far my favourite modified bike on the planet. Love the continual development :biggrin:
