class B fork & wheel queries
 

Hi all

had search and i think i know the answers but thought id check to see there aren't any changes

Forks

I see some riders use the 696/796 non-adjustable showa forks with radial callipers
can i confirm these are legal in class B

Wheels

are the 5 spokes from wheels found on the monster s2r/s4r legal? or do they need to be the 3 spoke type only?

as i understand it the later style 3 spoke wheel are lighter/better made how can i tel these parts

thanks in advance

alasdair

Yes they are Legal for Class B, to my knowledge the only rider to have run them is Hugh Simpson


NO the 5-spokes ARE NOT Legal as they never came in the 600 or 620 models


Tha alloy is know where nar as soft so does not distort as easily with the later wheels.
Early wheels - the spoke gets wider where it meets the rim
later wheels - the spoke gets narrower where it meets the rim

thank you sir much appreciated

Left = early, heavy
Right = later, light

The lighter wheels are not necessarily better, depends on how you ride.
The heavy wheels give you a tad more inertia which can be useful, ie up the hill to the hairpin at Brands or the first left at Cadwell. OK they may take a little bit more braking as a result but this lends itself to smoother flowing riders as opposed to point and squirt methods.
Running twin discs has the same effect.
I swapped from heavy to light wheels and to be honest couldn't tell any difference (*maybe because I'm such a smooth corner demon :o ) so don't fret if you don't find a set.







*or just not good enough to tell them apart.

thanks gents, I'm sure what i have have will do the job fine, especially if i get the suspension setup right

i know from the bigger bikes a lighter wheel does make the bike turn in easier so will keep an eye out for a cheap set , they seem common enough on ebay
shame the 5 spokes aren't allowed, got one few kicking around from the monster and 998
guess the SBK ones are a bit lighter but i doubt the s2r/s4r ones are any lighter than the later 3 spokes

the bike has twin twin discs already but I'm debating running with a single disk and caliper.although I'm not small and do like a powerful responsive brake so might need some pre season testing

wtf
 

WFT are you on about Scott?

Think he is on a legal high;)

badger bait?

Think I may have been a tad tipsy!
Just some stuff an ex racer from round our way said to me, apparently he always changed to heavier wheels and discs at Cadwell and Brands.
Kind of makes sense after a large portion of giggle juice.
